Modern day technology has added another tool for the genealogist
to further improve the accuracy of research results.
DNA testing can be an aid in determining if certain branches of family names are
related or not (NOTE Y-Chromosome DNA testing is done to trace the male
ancestry). See Frequently asked
questions for an explanation of terms and questions.
The very first item that needs to be discussed is the misgivings that some may have about privacy and not wanting anyone else to know what their Y-Chromosome DNA profile is. To better explain this a little example will show potentially how many males have the same profile that you may have. Since the Y-Chromosome DNA is passed from father to son and on average a change may occur every 500 years or 20 generations then using this as a starting point and assuming that a family has 12 children with half boys but only half of those live to maturity and reproduce then on average there are 3 males added to the population from each male that produces the next generation. At the start there is 1 male then 3, 9, 27. ... and after 19 generations there would be 1.16 billion males all with the same profile. However, the minimum number could be just one and you are that person. This is completely unrealistic but this example shows that the Y-Chromosome DNA profile is not a private thing like the DNA profile that is done to show paternity or to solve crimes which is unique to the individual. The table shown on the right hand side shows this effect for different males per generation that live to maturity and how the male population would grow after n-generations. The other factor that we as individuals owe to our children and the rest of society is that our line might be dying out as far as males are concerned and only by having a profile will it be possible to determine the ancestral lineage for all the females that may still be descendants. We use tombstones so that others remember that we existed and the old wooden ones that were used in the early days are long gone and today nobody knows who the people were and any info on birth or death dates. With more permanent material the limestone tombstone seemed good but with acid rain it again is being eroded away and the information lost. Modern day granite and concrete are more permanent but again they have a lifetime as well. A DNA profile on the other hand holds the ancient story of our male ancestry and it does not deteriorate with age provided that a male is still living at the time when we want to test that line. Now is the time to test and preserve our ancestral heritage. In some ways, the "Certificate Y-DNA" which shows the profile is as important or maybe even more important then a birth certificate.
The first step to take if you want to use DNA testing to determine your male lineage is to follow the steps outlined in the following section. This description is being prepared to assist others who are searching their roots with various surnames but the overall method is the same for any surname.
This short description is being prepared to track my Y-Chromosome DNA testing to determine what Krause branches are cousins to me. A short description on the accuracy of Genealogy data is shown on this additional page.
How DNA can help trace ancestors: The female has two X-Chromosomes while the male has one X-Chromosome and one Y-Chromosome. When conception occurs the two Chromosomes from the mother and the two from the father split to produce a life with one Chromosome from the mother and one from the father. If the embryo has an XY Chromosome then the Y came from the father and that is the same way that the father received his Y-Chromosome, from his father. Thus studies have determined that by analyzing the Y-Chromosome DNA, the male ancestry can be tracked. This is explained more clearly in the following background page by Dick Kraus.
Todd Johnson discusses the fundamentals of DNA and some may find his information useful as background information
A Kraus/Krause DNA Project has been started by Dick Kraus (no relation to me as far as I know) and I joined the group in Dec. 2004, and have now received results of my DNA testing. For those interested in tracking the progress of the Dick Kraus DNA Project and seeing the results the recent story section of Dick's web page should be used. Information on the ancient story is also available from Dick's page. The Ancient Krause lines have been updated on Dicks database at WorldConnect. Branch-One Krause shown as one of the subgroups on the Kraus/Krause DNA Project is shown in the following sections. A recent addition to the Kraus/Krause DNA Project allows the results of all members to be shown and the area of the world where the earliest known ancestor came from. The Y-Results tab on the Project page shows these details. There is a world map shown below the table of values and at the top of the map is a button to select which Group you wish to view. this button is labeled "Please Select a Group". Click in this button and select the appropriate group(called Branch xxx) or "All Group Members" Only those members that have a location for their earliest ancestor and coordinates are shown. Use the zoom button shown as a "+" or "-" to zoom in or out and the left mouse button will allow you to move the map to view the desired area. The Haplogroups are shown in the colored scale below the map and the color of the balloons match the Haplogroup

Several Testing labs exist but the one that I have used and found very good is that of FTDNA which has Surname Projects that assist persons with different surnames when tracking Y-Chromosome lines. New groups are being formed to allow the searching of mtDNA lines and these are found from the same Surname Projects as shown above.
I would encourage other male members of the Krause branches (#1, #8, #23, and #32) that are from the Kreis Schlochau area of West Prussia that have been determined to live in close proximity to where my grand-father's family came from, to have a male member of their branch have a 37 Marker Y-DNA done so that it can proved or disproved any connections between the branches. Other Krause families that originated from the same general area of Kr. Rummelsburg, Schlochau and surrounding areas are also encouraged to have their DNA tested to determine if they also descend from a common ancestor that was in this area for an extended period of time (250-600 yrs.)
A scanned section of a map shows the location of the different families who are identified by the code numbers as shown by the small circles on the map. Family #520 should be shown to the right of #517 and would be located off the right side of the map as shown in another scanned version. Recently much of this map info is online from New Maps. The link for New Maps takes you to the page where you can select any map desired and then view it. The ones that I used are Gro(ss)Bblatt 40 & Gro(ss)Bblatt 41. I have the hard copy of these but now they are online.
512 Schildberg, 513 Richenwalde; 514 Elsenau; 515 Marienhof, Branch-23 [Branch Twentythree (also known as Branch-One-E) is the group from Marienhof, WPR, Germany(Ferdinand) to Minnisota, USA. A brother of Ferdinand, Carl Gottlieb Krause from ...................... WPR, went to Berrien Co., Michigan (a male descendant of this line had a Y-Chromosome DNA test and the results show a common ancestor to Branch-One-A). The Marienhof location is about a mile away from Friedrichshof where Branch-One was from.]
516 Kramsk; 517 Mauersin; 518 Friedrichshof, Branch-1-A (This is my branch located at 518, #517 is an uncle to my grand-father [DNA tests on this line would prove that the assumption that Herman was an uncle is either true or false]) DNA testing results have determined that an new branch called Branch-1-B is an exact DNA match to my DNA of Branch-1-A. This group is from Viartlum/Zettin area of Kr. Rummelsburg, Pommern, This area is just north of the area where the Schlochau groups are from(See map segment). It appears that his new group might be associated with the 'mother-lode' as this family has been in the same area for 250-600 years. Further DNA testing should give more information on other families that are descendants of this common ancestor. (Results of DNA testing received 9 May 2005) NOTE Further tests for the 25 and 37 Marker results showed differences at the following markers; 449, 456, and 570. However the first 20 markers were identical.
519 Friedland, Branch-32; DNA tests done on a member of this group show a difference of 1 at the second marker #390, the other 11 Allele numbers are the same as for Branch-One-A and Branch-One-B. These results indicate that Branch-32 has a common ancestor with Branch-1.
520 Waltersdorf, Branch-8 Branch-1-I Recent Y-Chromosome results have confirmed that this branch has a common male ancestor to the other Branch-One lines.
Posen (RedArrow) for Branch-1-F This member has just recently been tested and the information from his DNA profile are in the process of being analyzed and compared to the others in Branch-One.
All of these Krause branches that are descendants of a common ancestor are summarized on a page that shows the area where they originated in Prussia and Pommern (now part of Poland). See summarized page. (Includes Maps of Prussian areas where different families originated.)
Another member who appears that his line may be connected to the Schlochau Branches but is not shown on the maps is going to have his Y-DNA tested and the steps to be followed in this search are outlined at Solving the Puzzle.
If your surname is Krause/Kraus/Krauss then it is possible to check if I have your ancestral line in my database. At the present time, I am tracking 46 different Krause/Kraus/Krauss lines. If you find your ancestors in my database, aek740a, at WorldConnect then find which Branch-xx that you are associated with and then send me an email ( in the subject line of the email change the xx to your Branch number) so that I can keep track of which Branches are being tested.
If you are interested in joining the Krause DNA Project. To join the project,
just go to the following page and fill out the request form.
The following example is based on an email that I sent to a member of a Lane group whose ancestors came to Calais, Washington Co., ME, in 1805 and are looking for earlier Lane ancestors possibly from the Lane families in MA.
My suggestion is that maybe you have your DNA analyzed 37-Marker to establish ancient history as well as more recent. The cost is about $230.00 US To give verification to your DNA being the same as your earliest known Lane ancestor then have another male descendant from a son of this first ancestor also have his DNA tested. That way it is only your Lane branch that is being tested. When the results are compared, you may find that someone from the MA group have already had their DNA analyzed and that will tell you how close the match is to your group.
To see what Krause names have already been tested just go to the following URL: http://www.ysearch.org/
Now do the following: (Test for your own name by replacing the name Krause by your name in the following explanation.)
When testing for the Y-Chromosome DNA there are three different test
processes that test for either 12, 25, 37, or 67 markers. Many persons being
tested use the 12-Marker test and that would seem to be sufficient but I
have found that this is just a start and the more markers the better. In
helping an individual whose father was adopted but the birth certificate for
the father indicated the name of the grandfather. Based on this information,
I first assumed that it would be a given for DNA testing to prove that this
was the correct lineage. Since this person already had his 12-Marker DNA
results then the ancestral line would be simple to find. However, when a
match of all persons with the same 12-Marker DNA results turned up 102
persons and only two with the surname of the expected line, it became
apparent that the 12-Marker DNA was insufficient to show the lineage as the
other 100 persons also matched and all those surnames were also possible
FTDNA has an eBook that explains how one should go about interpreting their Genetic Genealogy Results. This document is available here.
Final results of my DNA sample have now been
received and using the method explained in steps 1-9 above, my line is from
Haplogroup I2a1b2(ISOGG-2012): K. Nordtvedt. A better way would be to
show it as I-L161 as this will not keep changing like the other
designations.) for my Krause lineage and T2b4a for my maternal line( see
table below). A Figure of the
Haplogroup Chart shows how the human society evolved to present
day family units. There may be more information embedded in the
results but I am just learning how to read the data and more knowledge will
come as I become more familiar with interpreting the values.
A map of Europe showing the location of those who have the I2a Haplogroup
and submitted their data is shown at Y-search
of Europe. The red dots at grid co-ordinates 6 from the left side and 3
from the right side where 2 dots are just about on top of each other and the
third is slightly above and to the left are the locations of 3 members of
the Krause group who have been tested and found to have the same common
ancestor. The designation for this group is Haplogroup I1b1* according to Ken Nordtvedt.
Additional SNP tests have been done on my DNA and the results are shown in
scanned diagram of Ken Nordtvedt. The Yellow shows positive results and
the Blue are the negative results.
Results from the mtDNA are shown in the following table.
At the present time of those with test results in the data-bank, 73 people show the same identical values for the HVR1 results which means that we share a common female ancestor sometime in approx. the last 3000 years. Only 3 people show a match for the HVR2 with one of these showing a FGS(Full Genomic Sequence Match). One DNA cousin has been found using this method!!
A full study of the T2 Haplogroup has been done using persons(445) who had Full Genome Sequence(FGS) test results. The results of this study, done by Pike, Barton, Bauer, and Kipp, are now available and the 24 page PDF report is now available at the link shown..
Since my maternal grandparents were both from Norfolk Co., England, I have joined the East Anglia Geographic DNA Project. Maybe this will yield some results on the ancestral connections from my mother's side????? To see the lineage of my mothers side at WorldConnect just go to the link shown. My mother and Rosamond Geraldine Andrews were sisters.
The Male Descendancy Tree and how to use it for DNA testing:
The link from this section is an attempt to show how testing might possibly be done based on a Male Descendancy Tree. Examples are given for the case where only one member has been tested from each branch and known information on a Common Ancestor has been found from results of Y-Chromosome DNA testing. The other cases explained show how additional information can be gained if a second or third person from each line is tested. Male Descendancy Tree.
FTDNA has a new test called the Family Finder Test that is available for both males and females. This test looks at your complete DNA and compares the segments to test of others. If a match is found then by comparing the length of the values between the two people it is possible to determine how many generations back that the common ancestor lived.
All of those from Branch-One Krause who have had a 37-Marker Y-Chromosome DNA test from FTDNA, or in two cases, a male and a female descendant of Branch-1A3, are now being tested for this Family Finder Test. The preliminary results are being shown in the following tabular form that shows the person tested, identified as 1-A1, 1-A2, 1-A3, 1-A4, 1-B, 1-C,..... 1-I. The numbers in the cells indicate what the results were for kinship between the persons tested. If the number in a cell is 2/3 then that means that they are related by both a 2-generation and a 3-generation match or the Relationship Range. The next pair of numbers are for (Shared CM)/(Longest Block). No value in a cell indicates that no kinship has been found or the person was not part of the testing. The cells marked with an "X" indicate that you cannot be compared to yourself. A special chart showing the Y-Chromosome mutations for each Branch is available here. Cells marked with a "None" show no common relationship within the last 7 generations. If a "?" is shown then no data was shown for this relationship.
