William Frank Lean

I have just discovered that my grandfather, whom I did not know, lived in Bexhill prior to his death in 1984. He is listed in the 1982 telephone directed at Lt. Col. W F Lean and resident at 17 Merton Ct, Sutton Place. His 2nd wife I only know as Mrs E C Lean (nee Bass) and I believe in ’82 she was resident in Godstone.
I would be very grateful for any information regarding living relatives, gravestone inscriptions etc. Although born in Plymouth, he met and married my grandmother in Cape Town, South Africa, and later lived in Rhodesia prior to their divorce.
Currently I live in the USA, but would love to connect with any relatives on his side as I am trying to do my family history.
