A great many family members have started a family tree on Ancestry. One thing you have to do with hints is view the supporting documentation/sources. If you just pull in info from member trees you may get wrong information and make a mess of your tree and information. I know because I’ve done it. When evaluating member trees in hints. Always before inporting the information check out the sources. I am not saying to always ignore the information. If may give you a “hint” to dig a little deeper. Also don’t just add a source without verifing the information in the source. Ancestry supplies hint based on “best available” information. I would say maybe 80% is accurate. But there is that 20% that may be wrong. Bottom line, check the sources.
A few observations about DNA testing. I am finding very interesting information via DNA. Here is a little overview.
I did the Ancestry DNA test. Ancestry tests your Autosomal DNA which is pairs of 22 X and Y-Chromosome’s and one Sex.
I may do the Y-DNA (Y-Chromosome) at some point, Ancestry does not do Y. Males pass down the Y-Chromosome in it’s entirety from generation to generation. Mitochondrial DNA tests trace people’s matrilineal (mother-line) through their mitochondria, which are passed from mothers to their children.
You will get thousands of DNA matches. And Ancestry & My Heritage will show you how much Chromosones are matched. The higher the percentage the greater the match. For instance for mom there is this.
Shared DNA: 3,470 cM across 32 segments
Unweighted shared DNA: 3,470 cM
Longest segment: 203 cM
A centimorgan (abbreviated cM) is a unit of measure for the frequency of genetic recombination. 1 cM = 1% chance of a split/match.
Don’t get me wrong you can get matches on the Paternal side as well. For instance I have a match for a cousin that was adopted out. Born an Ackerman and was adopted out in the first year. I didn’t know about this cousin until 2020.
Shared DNA: 493 cM across 23 segments
Unweighted shared DNA: 493 cM
Longest segment: 55 cM
This is pretty definitive that he is my 1st Cousin 1x removed (my cousin’s son) whom we recently discovered. However I am unable to research him any further without knowing his birth father.
It is said that any match with less than 20 cM is unreliable. So tread lightly on those as possible. The key would be supporting source documentation.
There are many things you can gleen from DNA and I encourage you to go ahead and do it.
