I'd say 1930ish because of the children's clothing, the car and the fact your parents were married 70 years which would be around 1946. So your mom couldn't have married younger than 16 in my guess. 1925 was incorrect as someone else guessed. Ugh. I checked all your posts and no clues except your beautiful parent picture. I'm not sure where you are from but I know you live in BC now, so I'll guess BC as where it was taken.
