Infertility doctor secretly fathered dozens of children: how strangers became family

What defines a family? For a group of strangers, that question took on a profound, unexpected meaning after DNA tests revealed a hidden, decades-old deception. They discovered they were all half-siblings conceived through artificial insemination in the mid-20th century. Their biological father was not the man who raised them, but Dr. Charles Charny, a Philadelphia fertility specialist. In this week's episode of The Sunday Story, Frank Langfitt follows this unique family as they piece together their strange creation tale and decide to become a family.
