My father doesn't remember any of the details of his first wife, marriage, or the daughter. He is almost 80 and doesn't remember a lot of details any more.

I would assume they married in Vancouver as that is where he always lived.

He doesn't have the marriage certificate or the birth certificate. I have seen his divorce paperwork but it only lists her with his last name and the date they divorced.

I was going to order the marriage certificate but it asks for the date of the marriage but he can't remember when that was. Can you still get it without the date? How would I go about getting the Marriage Registration?
