Using Genome Mate Part 3 (Importing GEDmatch Chromosome Browser Data)

The previous article in this series is Using Genome Mate Part 2 (Importing GEDmatch One To One Comparison Data).

Thanks to some great programming work by Becky Walker, the developer of Genome Mate, there is a new option for importing lots of match data at a time into Genome Mate, using Sue Griffith’s method of an alternate to the GEDmatch triangulation tool for locating shared segments with other testers (as also shown step by step in my last blog post). In this blog post, I will walk through the new Genome Mate import process step by step.

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.

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.

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

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.

Introduction To Using GEDmatch

This is the first post in my series on how to use GEDmatch (http://www.gedmatch.com). 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.
