my mom's birth mother walked out on her and my grandfather. I want to know more about her family, if she had any other kids, if they had kids, did she have sibling and so on. My grandfather doesn't talk about it so I have very little information about her, but I have her full name, and approximate birth age. I'm looking for a way to search marriage and divorce and birth certificate records, but none of the websites seem to work. any info would help
