I did my first DNA test at 23andMe, I also have done DNA
testing at Ancestry, and I have uploaded my results to MyHeritage and FamilyTreeDNA.
Parallel to my DNA testing I was doing historical records
searching and have found documented proof of a DNA match with a relative with
whom I have common 2nd great grandfather. That was very exiting! Unfortunately
that relative have not responded to my messages. That is a common situation.
This did not discourage me, instead it just did an opposite it gave me a desire
not to stop and continue.
