I think your Mary Ann Stickley is on my family tree. Born 1874 (Tottenham) d. 1953 married Harry Cecil Baker Ewer?.
There's also a Frank Ewer who married another sister Florence Stickley and had 2 children Doris and Harry.
Does this sound familiar? I'm currently researching Mary Ann Ewer (nee Stickley)'s Grandfather James Stickley b.1808.
Please contact me on rich.natcook@ntlworld.com. I'm sure there is a connection.
