Hello - i searched and couldn't find my answer so maybe someone out there can help. I know who my blood father is but he was never married to my mother. The person I call my "father" legally adopted me after he married my mom when I was 10 so I have his last name. Do I post my "father" as my blood father or my "legal" father whose name I share? Or maybe there's a way to show both trees? Thanks in advance.
