Have you uploaded to GEDmatch yet? Lots of different spreadsheets there but I am having a little trouble understanding it all. Guess I will have to do some more studying for while. :oops:

Yep! I've uploaded my son's genome, my wife's genome, and my own genome. There are several ways to look at the data there, but it can be overwhelming. Where on the company websites you get dozens of matches, on GEDcom you get thousands.

Pay attention to the settings when you decide to generate a spreadsheet. If you pick 7 cM and 700 SNPs for your base you'll get matches from back before the genealogy data is available.

I've got 4 accounts that I manage -- my stepson's isn't uploaded to GEDcom -- and I've found that anything with less than about 15 to 20 cMs [higher would probably more useful] is so far back in time that it's useless unless you have standard genealogy data back into the 1700s and wish to confirm something. If you, like me, are struggling with people in mid-1800s the lower settings will swamp you with noise.

Now all this likely changes when you do a Dusty has and started using DNAGEDcom.com, but I'm not there yet and I suspect that you aren't either. We need to get Fred to give us a class on how to use that tool. Until I have more spare time I'm not going to spend a lot of effort on this tool.

What I have done [mostly] is to order up a spreadsheet, copy it to the clipboard, and download it to my machine. I can then paste it into an Excel sheet and sort it. If you're articulate with Excel formulae, you can ask specific questions of the data. But by sorting [low to high] by chromosome, start position, and end position you can do some stuff visually without a lot of code. For example: If looking at the spread of an entry any entry below that whose start position is greater than the end position of the proceeding entry and less than the end position is an overlap at that location on that chromosome [meaning that the subjects are related in some measure]. You can see that the task can get really tough. Hence, the DNAGEDcom product.

BTW: for a $10 monthly fee there are what is called Tier One features that swizzle the results in various ways. I've messed around with it but haven't spent enough time to give it a grade.

I just found out that the DNAgedcom.com is a different company from gedmatch.com. The donation of $10/month [from above post] goes to gedmatch.com from whom I get to use their Tier 1 tools. I mistakenly thought until this past week that they were the same company and that I had donated to DNAgedcom a year ago and they automatically charged my PayPal account for another year. I must have missed a checkbox or something when I signed in. Lesson learned: 1. they are different companies, and 2. be very careful when you donate something.

I joined one of those two last year and did the $10 Tier 1 deal but have not used it very much after the first month. Guess I need to check and see if they hit me for another 10 spot!

After sitting through a related meeting last week, I've come to the conclusion that there are too many ways to go after finding your relatives to come close to mastering all, or many, of them. I think I'll just find a method and go with the flow.

It's also pretty likely that the fun is in the process and not in the results. For example: I had pretty much given up on my own genealogy and focused on the wife's. It's more fun when you get some results from your efforts. Then yesterday I got a notice from 23andMe that I had new cousins -- that's a ploy they use to get you on the website -- but this time I saw a cousin with 21 segments in common and 6.29 cM match. That's either a second cousin or a 1st cousin once removed. His last name was a giveaway because it's the married name of my father's sister who moved away to marry a preacher in the early 1930. We have been out of touch for a couple of decades and now up pops one of her offspring.

Small world but getting more organized all the time, don't you think?

I use Ancestery.com and have found hundreds of cousins.
