Were your BARTLETTs in VA-WV-KY - if so please tell me more. My deduction is that William BARTLETT m 1800 Frederick Co, VA Lydia POWELL.They are in the 1800 Berkeley Co tax list; 1810 Berkeley Co census 30010-20100-00 (five ch born 1800-10, which is very compatible with m in 1800; and where I believe William's father was Garner BARTLETT, who had a lease in 1787 Berkeley Co); 1820 Frederick Co census (next door county); 1830 Montgomery Co (where the father, Garner, and brothers, Reuben and Thomas went); 1831 Floyd Co tax list; Lydia is then in the 1840 and 1850 Floyd (taken off Mont. Co in 1831) Co census near Leroy BARTLETT, b 1815, whom I believe was their son.
Leroy is the only name out of 10 chidren of William and Lydia that I've been able to tentatively identify, so your Ada Lourinda may have been in this family, too.
We need to find William's Will, probate, etc info in Floyd Co in 1830's.
It would help a lot if you provided any addtional info about Ada - birth date/place, marriage date/place, etc.
