My father was the oldest boy in a family of 6 (4 girls, two boys). One of his sisters was older. They grew up on a farm.
My Mom had one sister and grew up in a strict catholic family. Her childhood was pretty good, no history of abuse. Her father passed away when she was 14. Went to Ladycliff college (catholic college), then taught in a one-room-school house for 1 year, before becoming a bank teller. She then met and married my father who started abusing her about 1 year after they were married. Just about the time my oldest sister was born.
