Julie, My Grandfather was Henry Edward Offord, 1879(?) - 1962. He lived in Bexley, Kent. His sister, Ada, married Albert Worf and lived in Sidcup, Kent. He said that he was one of eight children and his father's name was Samuel. This looks like a pretty good fit with your information except that you list seven children in that generation. Incidentally, it's not North Gray but North Cray which is about 2 miles east of Sidcup and 2 miles southeast of Bexley. I have only just started my search and am very interested in your and gypsy's information.
