Hi Mike I am a descendant of Henry Bartlett's 2nd wife, Alethia Emerson (CLARK). My direct line is her 1st husband, John M. Clark who died before 1840.(I can't find his death date but she was head of household in 1840 Census) She was born in 1805 and died in Washington, DC on ___ 18, 1872 (March-May) and is buried at Glenwood Cemetery. I have a copy of her gravestone. Henry Bartlett was married to her on October 22, 1848 in Alexandria.If you would like to share informaton, please let me know. I don't have much on Henry but have a copy of a deed with his name on it.
