Hi Sherry, This is very interesting information.According to the 1830 Tazewell census, it show's Robert Allen and wife Betsy Kesky with 3 daughters and 3 son's.
Robert died in 1833 and by 1850 I can only find 3 son's and two daughters.
Betsey ( Roberts widow) married William Goolman Davidson the son of Joseph.If you noticed in that 1850 census Julia (dau of Robert and Betsy) is 19 and Mary is only 7.
In a court record regarding Roberts son John wanting to purchase Mary's portion of Robert's property, it mentions little Mary as an heir, through Sarah Allen deceased.So from that I assumed that on of those 3 girls was Sarah,and she must have had a child out of wedlock and perhaps died giving birth and why Mary was living with her grandmother and step grandfather in 1850.
Another of course was Julia, but I have no clue to the name of the third one or what happened to her.(Until now???)
I'm pretty certain that in the time frame your looking at the only Allen's in Tazewell were mine.
John b. 1770 father of the Robert above had two brothers, David Allen who moved to Greene Co. Indiana, but took all his children with him and they are accounted for.Thomas married Polly Brown. They lived on Bluestone near her people and in 1818 he sold out and went over to now Giles Co. VA.Thomas' wife's family the Browns were intermarried with the Davidson's, her sister Julia Brown married the brother of William G. Davidson, and I always figured might be how Robert's widow got together with William.
But going by the 1820 census I have accounted for the number of girls in his household.
So our best bet is the "Vicey" (Louvisa) could be the missing girl for Robert.
I'd like to know more about you line. Who was the father of the Samuel P. Davidson and what are the birthdates for him and Erastus?I know that William G. had a brother named Samuel Patton DAvidson, but did he also have a son named that? William G. Davidson was a widower when he married Robert's widow and I once read from a book that his children by his first wife really thought a lot of Betsy, but lost it before I got around to putting it into my FTM file.
I look forward to hearing from you.You can email me at winterbergs(at)suddenlink.net
