Before my dad met my mom he had a son with the woman he was dating at the time, he wanted to get married but she didn't and didn't want my dad around just for the kid. She pushed him out of her life and my dad moved on. He never told anyone except my mom. I didn't find out until i was 17 when we got a call from his grandmother to tell my dad that my brother's girlfriend had just had a son and my dad was a grandfather. I know very little about the history between my dad and his mom, I think my dad sent money over the years to help out, he was a trouble maker "like my dad". He kept in touch with me and my sisters for less than a year. The last I heard was he was in jail in Colorado I believe, for damage to a car. He got his GED and wanted to become a teacher. I have his name his sons name and his moms first and married name. Anyone experience this? Anyone know how to find a sibling. I love my sisters and I'm very close to them, i want to have a relationship with my brother as well. but i don't know how to find him. I've tried facebook, I've tried google, but i cant seem to find him. My dad wont talk about him.
