Honestly, I think the best thing to do is try searching facebook, and if she's of age now look in some phone books online phonebooks and wahtnot and try to find her. I mean give or take there'd be some time you'd never get to see your baby but
at least you'd get to meet your child.
I mean give or take, if I read correctly it was her parents choice to send her away and not hers. Don't be too upset with her. I'm sure things will end up for the best either way.
