While Paul Fronczak succeeded in reuniting a mother and son, there are still a few questions about his own identity. The Chicago Sun-Times tells us how during his search, Paul utilized a team of genealogists who helped him locate some of his own relatives and who he was. These include his parents, who were deceased, and some siblings, including a twin. Eventually, “Paul” found out he was really Jack Rosenthal.

You would think that once he discovered who he was, Paul (Jack) would have all the answers he needed, right? Wrong. As it turns out, there is now another mystery to solve. Remember how Jack now had a twin? According to The Sun, his twin sister, Jill, also went missing, reportedly after being neglected by their parents. He has now devoted himself to finding his missing sister. Paul’s (Jack’s) incredible story continues as he searches for the rest of the truth about his life before he was taken in as the Fronczak family’s son.
