I recently discovered that my sister and I do not share the same father, which is what we have been told our entire lives. I am not allowed to tell her this until I move out (she already has) because of family issues it would cause, but in the meantime, I would like to find out more information about her real dad for her.
All I know is that his name is Mike (Michael) and he lives somewhere in the southeast part of Michigan (near the thumb), or at least did in the 90's. He is at least in his mid-forties, but is most likely in his 50's, probably with dark brown hair (like my sister), and has a boat. Mike may also have green eyes, given that my sister's eyes have hints of green. My sister's mother's (who is also my mother) name at the time was Marie Claire Payne, though she most likely went by Claire Payne. She had brown, possibly blonde hair, brown eyes, dentures, smoked, and was from the Chicago area, although she may have been living in Michigan at the time. She also has a daughter named Jolene Payne, who was around nine at the time and had blonde hair and brown eyes. My sister was born on August 10th, 1992, which means our mother and my sister's father were together in late 1991, though my mother left before my sister was born.
Please, I know I haven't given much information about her father, but if you know anything at all, please contact me. I know this is going to be a huge shock to my sister, but perhaps having more information about her real dad will help soften the blow. Thank you so much for reading this. Below is the URL for a picture of my sister.
