My Mother, Penny Waight writes:
My father was called John Waight born 1902, he had two brothers, William (Bill) and Thomas (Tom). Their father (my grandfather) was a Merchant Navy sea captain who had retired to live in Jamaica and had a number of plantations there. His name was Thomas Charles Waight, he was born in around 1870 and died in Jamaica and my father John, his brothers William (Bill) and Thomas (Tom) returned to live in Greenwich, London with my grandmother (Nanna Waight). Thomas Waight (1870's) was a member of the Moore Keys, Kingston Masonic Lodge, Jamaica and accepted degree there in 1830ish.
