Looking for older sis [in her 20s ; black white puerto rican ]

My name is Maddii. I'm looking for my older half sister Faith . My mother Marlene had a baby girl right around 1986-1988. It was a closed adoption. My mother was very young when she had the child. I believe im looking for a black white and puertorican woman. All my mom could remember is she had the signature nose all her kids have. Sorta looks like a volkswagon hood chubby. Well sis if your out there ; i cant wait to meet you & i hope your lookinq for us too. You got 2 half brothers.
