Hi GeorgiyH
Re:
LUFF family (Owen Street, Wellington).
I can't see anyone actively researching
Melville LUFF, although there is a "tree" at ancestry which names his parents, but gives little additional information (e.g. no spouse named).
I believe he was the only child of George LUFF (bc 1897, Islington, London) and Leonora Vera WOOD (m. 1922 - NZ).
[If you search PapersPast using his parent's names, you'll find details relating to young Melville being taken off to Australia by his mother. The newspaper articles refer to the child as "Mickie" - perhaps to protect his real identity.]
Melville George LUFF (b. NZ circa 1925) appears on the Island Bay, Wellington, Supplementary Roll of 1946, occupation, welder, residing at
126 Owen Street. His father George LUFF, cashier, is on the main roll, at same address (and also his grandmother, Elizabeth LUFF).
It appears that Melville George LUFF married ... and possibly had two children ?
The Wellington City Council Cemeteries database has a listing for his death in July 2001 - along with a photo of his headstone at the Makara Cemetery. The name of the Funeral Director is also given on this record.
It's possible that by contacting the Funeral Director, you can obtain further information on next-of-kin. [Or Karori Cemetery office may be able to assist ? ]
