Later Peter Still sought help at the Pennsylvania Anti-Slavery Society, seeking to find his parents or other members of his birth family. He met William Still there, but initially had no idea they were related. As William listened to Peter's story, he recognized the history his mother had told him many times. After learning that his older brother Levin was whipped to death for visiting his wife without permission, William shouted, "What if I told you I was your brother!" Later Peter and his mother were reunited after having been separated for 42 years.
