I have found a marriage that fits most of the information I have to but wondering just how much is enough 
Henry William Taylor Townsend was born 15 Oct 1855 to parents
Samuel Luke Townsend a surgeon and Louisa Taylor
Louisa died 1861 by committing suicide and Samuel died in 1866, never found Henry in the 1871 census but have found a marriage for a Henry Taylor Townsend born 1855 with occupation of surgeon his first name is a bit unclear but could be William.
Is this convincing enough
