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...

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).
