There is a Birth Reg June 1881 and Marriage Reg for Alfred William Byles but he does not seem to appear on the 1901 Census under that name.
in 1901 could he be under FREDERICK Byles, Nephew, Lodging with the Mead Family (William/Emily Mead).
Fredrick is born c 1881 Buckhurst Hill, Essex, Occp Plumbers Labourer.**
A James Byles 1873 is there also, Occp Plumber
(I can find no Birth Reg for a Frederick Byles)
