It has been my experience that generally the first name stays the same but that the last name gets changed to the adoptive parents last name.
I recently talked to an adoptee who was relinquished at three and she remembered the names of her birth siblings, aunts, uncles and birthmother. It's amazing sometimes what a small child "stores" in their memory bank!
