searching for my sister Paige Lynn Thompson and brother Alexander!

Im looking for my sister Paige Lynn Forrester (adopted last name is Thompson). She was born april 3 1997 in Missouri I believe. She was adopted in Texas! She has one full brother Alexander, the rest of us are just half siblings! I don't know much about Alexander because I was taken away before he was born! Our mom passed away a few months ago in Texas and she would never talk about why Paige got taken away or when. I remember talking to her on the phone and then suddenly she wasn't with my mom anymore.
