Follow Friday: Hoosier Daddy?

In his blog Hoosier Daddy?, Michael Lacopo writes about his search for his mother's father. His mother was adopted as a baby. He eventually found his mother's biological mother and her family, and he thought he knew the identity of his mother's biological father. However, DNA testing revealed that her mother's father was neither his grandmother's first husband nor her second husband. Through DNA testing, Michael narrows down the list of possible candidates for his grandfather. Along the way, there are some surprises. I eagerly await additional posts, and I also want to know the identity of his grandfather!
