Hi Dolly
I'm getting addicted to this family line, I have them in 1861 at 21 Bowling Street, St Johns Westminster.
George Treves (as before) age 40
Mary Ann (as before)
William (as before)
Emma daughter 8 Pimlico Middlesex (this could have been "Rianna" in 1871 as its unclear)
Jane (as before) age 6
Elizabeth 6 twin
Richard (as before)
Charles (as before)
Frederick(as before, listed as three weeks old)
plus two lodgers.
RG9 48 19 31
the census states Jane and Elizabeth were twins but it looks as though Elizabeth died before the 1871 census. Might be worth looking up her death index in freebmd.
Best wishes
Amanda
