marymog, sorry, i thought i had replied to your question.
The details of the marriage certificate are; 8 Nov 1856, George Moseley L, full age, bachelor, gent, 41 Gloucester st , father - George.
Honora Scanlan, full age, spinster, 41 Gloucester st, father - Michael Scanlan; married Registry office, St Pancras.
Honora's death from pneumonia, 23 Jan 1858, age 37. The informant was Biddy Dornin (signed with a mark) curious??
The 1851 census has her age as 20, born Ireland.
There is an Eleanor Lander in the 1851 census:-
HO 107/143?; 3 Abbey Terrace, Marylebone
household of James Gerrish, 55, Elizabeth Gerrish, 38, 6 children, 2 gr children, 1 f s.
Eleanor Lander, sister, age 12, born Oxfordshire.
Age fits, & she is the only Eleanor that i can find that is about the right age & not living with parents.
The only other thing that might fit is that Eleonor was an illegitimate daughter.
bryn.
