Marriage lookup for William Doughty, born 1773, died 1859 - worked as a naval architect at the Washington DC naval yards. I am led to believe he was married 3 times! 1st to Eleanor Wilson in 1795, then his 2nd marriage to Eliza Wild in 1844
His 3rd and final marriage was to Mary Ann (maiden name unknown) after 1850.
From the 1850 Census, he resides with Eliza Doughty (Wilde) - 24 years his junior, and her daughter (his step-daughter) Ann J. Wild - both born in England.
His last Will and Testament in 1859 notes his current wife as being Mary Ann. It also mentions his step-daughter Annie Wild.
I am unable to find any evidence of the latter 2 marriages to Eliza or Mary Ann. Or any evidence of Eliza Doughty's (Wild) death (anytime between 1850 and 1859).
