There are many companies that offer DNA testing. The two that I have used are 23andme & ancestry.com. Ancestry.com has updated their basic test of years ago so I had a new one done which is much more extensive. The new test does not give you your haplogroup which is a disappointment (I sent a complaint/suggestion to them). I wanted to check it against the haplogroup from my 23andme test.
The problem with all the companies available is that they all have their own databases & their own tests & their own interpretations of the tests. Nothing is standardized. There are ways to compare your test results with other databases.
We have recently (May 2016) started a comparison chart using GEDMatch (they compare DNA tests done by different companies). If you upload your DNA test to GEDMatch they will assign you a kit number. Send your kit number to me and I will add you to the chart. The more kit numbers we have, the more matches we find–especially between descendants of the two main branches from the two wives of James Taylor I (only one good match so far).
So if any of you are thinking about getting your DNA tested I would still recommend ancestry.com. Watch for sales and it is only $80 (plus shipping)–recently it was on sale for even less– as opposed to $99.00 ($108.95 including shipping). If you have a family tree at ancestry.com you can link your test results to your tree and it will help you find matches.***
FOUND & PROVEN MATCHES (on ancestry.com as of 15 Sep 2014):
Common ancestor James Taylor IV:
Steve Taylor (paternal haplogroup R1b1b2a1a1d1, maternal haplogroup T2b)
Betty (Taylor) Merz
***I have 290 pages of matches on ancestry.com with about 30 per page. I have found 5 that descend from James Taylor I. I have one hint page of supposed Taylor cousins. Those 5 were on the hint page along with 26 others; 22 with faulty connections to the Taylors. Remember that genealogy is only as good as the person’s research. Many people just copy and paste or invent connections. The 22 are probably my cousins (just not cousins through the Taylors) and four of them have private family trees so I can find nothing about them. I have never understood why people pay good money to ancestry.com or any of the other subscription site & then have a DNA test done and link it to the site AND THEN MAKE IT ALL PRIVATE!
