Sorry, My Father's name is the same as his father, Chelmer John Gray, aka Charles John, Charles Joseph and Chelmer Joseph. Affectionly known as Jack in Australia. I do not know the names of his half sister and brother nor the name of his Canadian wife or what part of Canada she died in. I have no information on the date of my Grandmothers marriage to Mr Peterson(?) nor when or how they went to Texas. My father died in 1953 in Mossman Qld, Australia.
