Update: I found the obit for Ernest Sinclair of Courtenay, BC). He died 11 June 1996, Comox, BC. He was survived by his wife, Edith (Foster). Then in 2009, Ernest's sister, May, passed away in NB. She was survived by sister-in-law, Edith Sinclair (Courtenay, BC).
Then I received a copy of an article written in 1995 by Edith Sinclair. She wrote about Mountain View Cemetery, Vancouver. She said both her parents are located there, in what they use to call the new section. That area is known as Abray Park.
I am searching for Edith Foster's parents names, brothers, sisters, etc. Any help would be greatly appreciated.
