Using GEDmatch Part 5 (Alternate To Triangulation Tool)

The previous article in this series is Introduction To Using GEDmatch Part 4 (Alternate Way To Find People Who Match One Or Both Of 2 Kits).

This week, I happened to come across a fantastic blog post by Sue Griffith. In her post, she demonstrates an alternate method to the GEDmatch triangulation tool for finding overlapping segments. I really like her methodology, but the explanation of the steps seemed like it could possibly be a bit overwhelming for some people. With this post, I want to walk through Sue’s method step by step, providing additional information and screenshots, so others can also begin to take advantage of her great way to find segment overlaps.

Adding A GEDCOM File To Genome Mate

The previous article in this series is Downloading A GEDCOM File From An Ancestry Member Tree.

Now that you’ve successfully downloaded the GEDCOM file containing the ancestors of the test taker, this file needs to be imported to Genome Mate so that we can begin to make use of some of the advanced tools in Genome Mate. This post will show how to import a GEDCOM file to Genome Mate in simple, easy to follow, steps.

Downloading A GEDCOM File From An Ancestry Member Tree

The previous article in this series is Introduction To Genome Mate.

Some of the most useful features of Genome Mate require a GEDCOM file of the ancestors of the person who took the DNA test. In preparation for learning to use these features, we need to get a GEDCOM file of the test taker’s ancestors imported into Genome Mate. In this post, I will show how to generate a GEDCOM file from an Ancestry.com Member Tree, since I’ve found many people don’t seem to be aware this feature exists.

Using GEDmatch Part 4 (Alternate Way To Find People Who Match One Or Both Of 2 Kits)

The previous article in this series is Introduction To Using GEDmatch Part 3 (The People Who Match One Or Both Of 2 Kits Tool).

As I mentioned in the previous post in this series, for some unknown reason, there are times when the GEDmatch People who match one or both of 2 kits tool does not properly report the matches between the two kits. In this post, I will show you how to conduct a check for common matches between two kits using a spreadsheet. This allows you to double check the GEDmatch tool, and has the advantage of providing you with the ability to save your results and/or check for common matches among more than two kits.

GEDmatch and GenomeMate Resources

I’ve read that it’s estimated 80% of genealogy is repetition. Repeating the same research someone else has done, repeating our own searches over again, and reviewing the same sources that others have already gone through, for example. I have little doubt this estimate is likely to be quite realistic. I’m certainly guilty of this repetition just as much as anybody. This repetitiveness also exists with genealogy blogs.

Using GEDmatch Part 3 (The People Who Match One Or Both Of 2 Kits Tool)

The previous article in this series is Introduction To Using GEDmatch Part 2 (The One-To-Many Comparison Tool).

It’s taken me awhile to post another article in this series because I was hoping the Triangulation tool would be reinstated by now. Since it has not, let’s explore the People who match one or both of 2 kits tool that has recently been reinstated. For each of the matches we get to our kit using the ‘One-to-many’ matches tool, it is very helpful to know who else happens to match both of our DNA tests. This can help us begin to identify shared segments between at least three people, forming the basis for properly triangulating the segment back to a common ancestor, or set of ancestors.

Using GEDmatch Part 2 (The One-To-Many Comparison Tool)

The previous article in this series is Introduction To Using GEDmatch.

Now that we know how to do ‘One-to-one’ comparisons at GEDmatch, and the importance of doing triangulation on matching segments, let’s take a look at the ‘One-to-many’ comparison feature available on the GEDmatch website. The ‘One-to-many’ tool will give us a list of our closest DNA matches found on the GEDmatch site. Continue reading

Using Genome Mate Part 2 (Importing GEDmatch One To One Comparison Data)

Now that we’ve covered the fundamentals of triangulation of DNA test data and how to do one to one comparisons of DNA tests at GEDmatch (as shown in my previous article, Introduction To Using GEDmatch), I want to show how to import this comparison data into the Genome Mate software. In this blog post, I will walk through the process of importing GEDmatch one to one comparison data into Genome Mate, step by step.

Wade DNA Test Results

The Y-DNA 12 marker test results of the descendant of the George Wade family of Monongalia County, Virginia (now West Virginia), have come back and are now posted on my Wade Y-DNA Test Results page. There were two exact matches who shared the surname of Wade (or a variation thereof). One of these matches had a family tree connected to his test results, and I can clearly see he is also a descendant of George Wade, and he was kind enough to give me permission to include his partial lineage on my website. He is descended from a different son of George Wade than the descendant I had take the test, and they are both descended from a different son than my line descends from. Provided this match continues to hold up when refined to 37 markers, or preferably 67 markers, these results will go a long ways toward verifying the lineage back to George Wade, and subsequently trying to verify the correct ancestral family of George so that the line can be extended further back in time. This gets things off to a very good start.

While I have little doubt this match is accurate, given the vast amount of research and documentation available for the Monongalia County Wade family, for future comparisons against other potential Wade ancestral families, the match needs to be confirmed to at least the 37 marker level, and preferably to the 67 marker level. I’m working with the match to see about doing this test upgrade. In the meantime, the other match had no family tree connected to his results, and an email address that is no longer valid. I believe I have located an updated email address for him, and am now waiting to hear back as to whether it is indeed him, and if so, what his lineage is.

Pendleton County Stone Family DNA Test Results

The Y-DNA 12 marker test results of the descendant of the Stone family of early Pendleton County, Virginia (now West Virginia), have come back and are now posted on my Stone Y-DNA Test Results page. Even though the Y-DNA 12 marker test is a very basic level of testing, there are enough differences (5 out of 12 markers) that a close connection between my Stone paternal line and the paternal line of the Pendleton County Stone family is very unlikely. While it’s always a bit disappointing not to discover a match, negative results like this are a great help in knowing where to refocus future research for trying to locate the correct ancestral family of my Stone paternal line. These results also let me know that the Rexrode/Rexroad matches I’m seeing in the autosomal DNA matches of my father and myself are very likely related to my Varner ancestors, and not to the Pendleton County Stone family (who also has ties to the Varner family).

The next step is to test a descendant of the Stone family of early Greene County, Pennsylvania, who I also feel is a strong candidate to be the ancestral family of my Stone paternal line. I’ve already received a lead on a potential tester, and am just waiting to hear back from him. Hopefully, this family will be a match, as this is the last of the Stone families I’ve identified in the immediate area surrounding where my earliest Stone ancestors lived in Monongalia County, Virginia (now West Virginia), .
