Roseanne Gilpin (Fones), and brother Lea were among the last residents of the ghost town Triadelphia. Their father Fred Gilpin managed the farmlands for P. G. Ligon until 1941; a year later the Washington Suburban Sanitary Commission acquired the land for the new reservoir.

Lea Gilpin, Roseanne's brother, plays with terrier Heather outside their stone Triadelphia home.
