I have been looking for my half sister for over 15 years. Her maiden name is YVONNE PENA. It is quite possible she now uses a married surname. She was born in New York City on 2/14/60. Her father's name is Maximino (Max) Pena and I believe he still resides somewhere in Bronx, New York. He also has a brother named Carlos Pena. Yvonne's mother's maiden name is Nylma Ortiz. However, it is very possible that Yvonne may not know of my existence or even know that her biological mother is still alive. We were separated in 1965 when she was taken away by her natural father. I do have several photos of her as a child. I also have photos, as well as 8mm film footage, of her mother and father from the late 50's. Any information would be greatly appreciated. Happy Birthday Sis, wherever you are.
