Have you heard the big hubbub going on in genetic genealogy circles?  Ancestry will be dropping your 6 and 7 cM matches from your match list. In my case, I have 192,306 DNA matches at Ancestry. Of those, 54,498 matches are below 8 cM meaning Ancestry will drop over 28% of the the people on my ...

A very exciting day for me today, as most of you reading this will relate to. A second cousin of mine who I know showed up on my 23andMe match list. She matched me with 3.1% = 234 cM on 19 segments, which is exactly where she should be according to The Shared cM Project tool. I have 9 other cousins who have ...

I’ve written over 1100 genealogy-related blog posts since I started blogging in 2002. But very rarely have I written about my own genealogy research. It’s actually going okay now.

I very recently wrote a blog post about Kevin’s site. Kevin also has a blog in which he has been posting very interesting articles, ...

On Facebook, I was delivered a sponsored ad for getting health reports from your DNA raw data at a 55% discount from a company called Xcode Life. @xcode_ls I’ve always been much more interested in DNA for genealogical purposes than for health, but I had never heard of this company and it sounded ...

There’s another website I recommend you upload your DNA raw data to called Borland Genetics. See this video: Introducing Borland Genetics Web Tools In a way, Borland Genetics is similar to GEDmatch in that they accept uploads of raw data and don’t do their own testing.

OneDrive's default setting of no limit for network upload and download rates has caused years of Internet problems at my house. Unbeknownst to us, it would from time to time consume most or all of the Internet bandwidth affecting me when on my ethernet connected desktop computer and affecting everyone else in ...

These extracts each contain about 2 million SNPs that are tested by the five major consumer DNA testing companies: Ancestry DNA, ...
