RG14 Piece: 28338
37, william Street, Allerton Bywater
Benjamin Armstrong age 56, b. Staffs
Hannah (wife) age 51, b. Little Lever, Lancs. 9 children still living, 3 children have died
Maud (dau.) age 21, b. Altofts
William (son) age 19, b. Normanton very confusing...1887 Walter became William, now 1891 Walter becomes William too!!!
Herbert (son) age 15, b. Bowers, Allerton
Samuel (son) age 12, b. Castleford
John (son) age 10, b. Castleford John Armstrong, registered 1901 Tadcaster
-I believe Martha married a Thomas Smith in 1902 Tadcaster
-James and Benjamin are lodging with neighbours in the 1911 census
-Walter/William is married and living in Normanton in 1911 (place of birth Altofts)
-I can't find Hannah/Harriet in the 1911, but I think she married late that year to Hubert Wilkinson, Tadcaster
The 1911 census says Hannah/Harriet has 9 children living.... but I make it 10 . Something tells me I've got into a muddle somewhere, but I'm not sure where so hopefully somebody can help shed some light.
Thanks in advance,
