This is probably a good reference point for everyone, even myself.
For a brief explanation:
Mom and dad never married
Dad had my brother, then got married and had a boy, two girls and another boy
Divorced after 21 years
Mom got married, had a boy and girl
Divorced after 3 years
Married a man with two sons the age of my brother and sister
Divorced after 4 years
Married a man with twin autistic boys
Still married
My Paternal grandparents had 11 kids, I have one aunt that passed away, Total they have 50 grandkids
>>Fun Fact, THIS grandpa had a twin brother, they lived next door and he also had 11 kids
My Maternal grandmother, she has one other daughter. My mom and aunt have different dads, neither of their fathers are the man my grandma was married to at the time. I have never met my grandfather. I asked once when I was little why I didn't have a grandpa there, and the answer was "because we just don't."
