Charting the atDNA matches

I sent out a massive spreadsheet with charts of those who matched myself, my father and cousin Jeffrey hoping to spur further research and collaboration.  I tentatively called the spreadsheet "LeMaster atDNA", even though many of these matches will turn out to be cousins that share other uplines.  At the least, since the common ancestry of dad, Jeffrey and myself is Luman Cooper LeMasters and Barbara Isabel Wehrly we know that these matches are cousins somewhere in the upline.

My sheets had a page where all of the matches were listed, then a table showing how I had compared each match to each other and how many segments and centimorgans were shared.  Still another chart had the total amounts of shared DNA mapped out with the chromosome and the start and end point.  Each chromosome had its own separate sheet of data where I graphed out the overlapping segments.

At first glance, chromosomes 7 and 15 seem to have a lot of overlap amongst the group of people I've been able to compare.  I'm so thankful for sites like GEDMatch - i just wish more people would upload their results.

Only one email address from GEDMatch was a bounce, and I've already had a reply from someone who is helping, Danny, the gentleman who reached out to me earlier.  Danny's paternal ancestry is a unknown to him at this point, and that is where we match, so this will be an interesting journey.

Sometime I hope to get more into DNA, but it won't happen for awhile. I did the DNA test, I believe, on ancestry.
