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), .

Introduction To Using GEDmatch

This is the first post in my series on how to use GEDmatch ( My goal in writing this post is to provide an introduction to using GEDmatch to do comparisons, and explain the basic fundamentals of chromosome mapping, in an easy to understand manner with simple to follow instructions.

Introduction To Genome Mate

In preparation for my series of posts on how to use GEDmatch, I recommend you download and install the Genome Mate software ( While not mandatory for using GEDmatch, or following along with my posts on GEDmatch, I think you will find it will make things much easier. Continue reading

An example of why Ancestry DNA shared ancestor hints need to be verified

To better illustrate why the Ancestry DNA shared ancestor hints should be used only as a suggestion of where the possible connection may be with your DNA match, rather than something taken at face value as confirmation of where the connection is with your DNA match, I wanted to create an example to show how a shared ancestor hint can be completely wrong and misleading. As you can see, in the list of matches for my maternal grandmother’s brother (R E H), he has a shared ancestor hint with both myself and my mother, as indicated by the leaf next to the number of people in our respective trees.
