Douglas said to have married Elizabeth See - I've not found a marriage. He is said to have died 1843 in Missouri.

Anthony & Douglas & John were all in Missouri in 1840. One of them apparently had a son Haden because their brother Haden was still in Kentucky. On the same page with Douglas is:
Haden Wyatt 2m -5, 1m 30-40, 1f 20-30

1850 Census. Warren Co MO Hh 148. Between the family of Douglas Wyatt, age 32, b. KY and Haden Wyatt, age 44, b. KY.
Elizabeth Wyatt - apparently the widow of Douglas - age 68, b. VA
Elizabeth Bowls, age 5, and Martha A. Bowls, age 4, both b. Missouri
A Mary Margaret Bowls married Thomas "Bowels" on 11 Aug 1842 in Warren Co.. Perhaps a daughter of Douglas & Elizabeth that is now deceased. These two little girls could be hers. I also believe Douglas & Haden living on either side were likely sons of Douglas & Elizabeth.
