Joe Villegas and Lindsay Smith of Fort Worth, Texas had four children.
But Lindsay's brother Ryan, and Joe's sister Amy are married and have been unsuccessful in having a child.
So Joe and Lindsay had a baby and gave it to them to adopt.
Lindsay now says that she considers herself Christopher's aunt, rather than a mother. The adoptive parents both said that they were very happy for the gift of a child, that so closely resembles themselves.
Because Christopher Ryan Smith's adoption is independent, no agency needs to be involved.
