I need to know how I can find my niece, Tasha Fry, she has aunts, cousins and a sister, who want to know where?

Tasha was adopted more than ten years ago. We don't know who, or where she is. She was about 11 years of age, born in Bronx Ny. She would be about 29 or 30 years of age. She had an uncle named Erwin, aunts named, Monica, Debbie, and Chriss. She has cousins, Emmanuel, Tudy, Lauren, Freida, Danielle. She would probably be living in Bronx Ny, but could have moved. Her last name may have been changed. If anyone has any information please contact me.
