Cottrell was a traditional musician and craftsman from Clay County. He came from one of the area’s earliest families and was known for his woodworking skills. He made toys, chairs, canes, and banjo rims using parts from old Buick cars. He also was a well-known banjo player during the folk arts revival in the 1960s.

Cottrell lived his entire life on Deadfall Run with no electricity, running water, or phone. He lived simply with his sister Sylvia O'Brien, who was also a musician. Proud of his heritage, Cottrell shared his music and craft across West Virginia and beyond.
