Your answer is Ken Davidson of California.
Joshua Davidson Junior obtained a marriage license July 13, 1786, and married
Mary McDearmon, daughter of Dudley Mcdearmon September 26.
George Davidson, younger brother of Joshua, married "Creasy" (Lucretia) M
cDearmon, daughter of Dudley McDearmon "who consents, February 9, 1790. These
two Davidson brothers were sons of Joshua Davidson Senior and his wife Sarah,
who named them in her WILL in 1808. (Geo., 7 Lucretia, my line!)
Sarah McDearmon, daughter of Dudley McDearmon, married Alexander Womack December
27, 1798. (Probably Alex., Junior).
This accounts for three of Dudley's nine white souls enumerated in 1785. Some
of the other McDearmons recorded in Prince Edward County may have been Dudley's
Dudley's wife may have been the daughter of James McMacklin who, in 1754, served
on the jury with Michael McDearmon. Lucretia's second son, Bracket Davidson,
named one of his sons Milton McMacklin Davidson in 1830.
