I am an only child too.
Grandparents: My maternal grandparents had passed away before my Mother and Father even met each other. My paternal Grandfather died when I was 5 months old. My paternal Grandmother died when I was 29.
Parents: Mom passed away on April 30, 1997 just about a week before my birthday. My Dad is still here and thankfully seems to be healthy. He will be 80 next week on the 28th.
My Mom had a sister who passed away when I was 5 and a brother who passed away when I was 6. She had another brother who was the oldest by 15 years and outlived all of them. He died about 5 years ago.
I have 2 cousins from that oldest brother and I never see them.
My Dad had a brother who drowned when he was 10 years old. He had another brother who was killed in WWII. He had a sister who was the youngest in the family who died 7 weeks to the day after my Mom had passed away. That was rough. I felt so bad for my Dad during that time.
He has another sister who is married and I have 4 cousins from them. I only see them on holidays and such but I have 4 second or is it third cousins from them. My oldest cousin had 2 boys and we were never very close to him and his wife or should I say ex-wife .
The oldest of his boys graduated from college last year and I think that the younger one is in college.
The second oldest female cousin has 2 kids. One girl who I always remember at Xmas time and is now in college and a boy who I also remember at Xmas time and is now going to be 11.
My other 2 male cousins are single.
That is about it.
