Dr. Herb Urkel is Steve's father whom was never shown on Family Matters, but he was mentioned a lot. It was stated that when Steve was born, Herb tried to push him back inside his wife's body. It was also revealed that he and Diane had nothing but the utmost contempt for Steve and do their best to avoid him at all times, which explains why he hangs around the Winslow family a lot. He has brothers named Cecil, Ernie, Omar, and Big Daddy Urkel. Herb has two sisters named Muriel and Oona (from Altoona). His nieces include Myrtle and Julie. His nephews are Cleotus, Dirk and Cornelius (OGD).
