The family of Henry Keller were residents of Boalsburg, Pa. in the 1800’s. Sophie Keller, daughter of Henry and Margaretta (nee Schneck), is significant because of her participation in a graveside remembrance at the Boalsburg, PA cemetery in Oct. 1864 that blossomed into an annual memorial day event now held in May. Collection covers sixty-two letters from 1837 to 1893 associated with the life of family members, including Margaretta’s kin, with many in the Civil War timeframe.
