After Tisha and her long lost half sister were united, later in the show, the two siblings were joined by Ellen's full-blood brother, Duane, who was actually the one who spearheaded the search for her. The siblings all share the same father and the oldest, Duane and the youngest, Ellen have the same mom. Tisha Campbell found out she had a half sister when she was 33-years-old.
