If you haven't already done it, look for his birth certificate and that will give a home address which would help us.  We would also then be able (hopefully) to find his parents in the 1911 census.
Try Family Search which is free or go to the local library and try Ancestry to get his birth date.  You can then apply either to the Registrar at the Town Hall, Loyd Street, Llandudno - assuming he was born in the area - for a copy of the cert.  Or General Records Office at Southport.  It's probably better and faster to apply to Llandudno.  I think it costs £14 now.
