George Garraway who married Clara Bell

George Garraway, probably born in the West Indies, married my distant cousin Clara Bell and moved with her to London.They produced at leats nine children, Alfred, Walter, Harry Weldon (Clara's mother was Mary Weldon), Alice, Margaret, Archibald, John(?John Archibald?), Charles and Hervey, and I'd love to know what happened to them and their descendants if any.
I THINK I've tracked down three generations of Harry Weldon's descendants, and I may just possibly have found Walter's wife (Winifred Kate?) and son (Leonard, killed in WW I) but the last two are NOT PROVEN.
