This is wonderful news.I assume you indeed do mean you submitted your own DNA, i.e. you had a mitochondrial (female) test done. And I assume you are referring to the younger Abbott Lee, the son of John and Elizabeth Nichols Lee.If this Abbott Lee and your Betsy Lee Alderman shared the same mother, that must mean that Betsy was a daughter of John and Elizabeth.(By the way, why do you call Betsy Lee Alderman "Sarah"?Or are you referring to a daughter of Betsy named Sarah?)
Your posts always confuse me because they are so brief. I thought at first you were referring to Abbott the son of Levi Jr. and Nancy Farmer.
I'm not a member of Ancestry and cannot look at their DNA results.Do you know if there are any male descendants of John and Elizabeth Nichols Lee who have done Y DNA testing? The information that's being unearthed is fascinating. Y DNA is showing relationships for which there is no paper trail whatever.
