Adelaide Advertiser, Tuesday 20 Feb, 1968
No death notice, only this funeral notice which at least shows she is his wife:
LUNNON. The friends of Mr Charles William LUNNON of 374 Brighton Rd, Hove are respectfully advised that the funeral service for his late wife, Florence Marion, was privately cionducted at the Sir John McLeay Chapel, Centennial Park Crematorium on Monday. Trevelion & Son, Brighton
There is also the death notice for Charles - he must have remarried:
Adelaide Advertiser, Wed 16 December
LUNNON Charles - Husband of Mary, passed away at his residence on December 12, aged 79 years.
No Funeral Notice.
Looks as though there were no children (other than Enid who died aged 10)
Cheers, Judith
