Pete Seeger was born in 1919, son of ethnomusicologist Charles Seeger.

Seeger re-married and, with the help of his new wife Ruth Crawford, produced four more children. Mike was born in 1933, Peggy in 1935. I believe (not sure) Penny was next (Married John Cohen, produced Sonja Cohen) followed by Priscilla. Priscilla chose not to be active in folk music. Penny passed away in the 1990s.
