Kylie,
Did you ever get an answer about your gGrandfather Stephen G.Bumstead? I've tried some other bits of this thread, but not yours, so I thought I'd give it a try.
FreeBMD says Stephen G's parents married in 1897, and so his father Stephen was probably one of two Stephen Bumsteads in
Hastings, born in 1871 and 1870 respectively who are recorded in the 1881 census. The two possible fathers were James W (b 1845), a fisherman, and Stephen (b.1829) a tailor. They were 3rd cousins, being both descended from Thomas Bumpsted (1700-1782). So by either route, (if the assumption from the 1881 census is correct) you are descended from Thomas' father, Edward (c1670 - 1702), the Original
Sussex Bum(p)ste(a)d.
I have the alternative pedigrees, but it would take more data to establish which is the correect line - ideally, of course, the father's name from the birth certificate of the Stephen
Bumstead who was born about 1870.
Best Wishes,
Chris
