I was surprised when I found out this wasn't automatically part of the divorce but I was OK with it because I never even met my biological father & didn't care to go back to his name either. Someone did tell me they thought I was trying to keep a connection to him when I didn't want to run out & change it but, luckily I don't care what people think. I would however rather keep the same last name as my kids instead of going back to my father's last name that I've never met. If I do go through all the legalities of changing my last name, which I still might; I would change my last name to my grandma's maiden name. She meant a lot to me & I know I meant a lot to her & my physical features are a lot like my maternal 2nd cousins. (My grandma's brother's kids).
