Can't see Benjamin Oakley on the 1891 census, but I think I have him on the 1901.
Looks like his first wife has died, and he has remarried. Children he has with him are Ethel M (17), Herbert (14), and Benjamin (5 months)
1911 - second wife might have died. Children with him are Ethel Maud (27), Benjamin Archibald Lloyd (10), Victor Lloyd (8 ), William Clifford Lloyd (5)
So possible descendants will come from:
John Oakley (bn 1878)
Harold Oakley (bn 1879)
Ethel Maud Oakley (bn 1884)
Herbert Oakley (bn 1887)
Benjamin Archibald Oakley (bn 1900)
Victor Lloyd Oakley (bn 1903)
William Clifford Oakley (bn 1906)
