Hi Janet,
According to the data I have, backed by census and newspaper accounts, show that your grandmother, Anna Foltz was the daughter of Obed Huntsberger Foltz and the grand daughter of Christian and Elizabeth "Betsy" Strite Huntsberger, his third wife. They lived in Hummelstown,Dauphin Co.,Pa. See:

Best Regards, John Foltz
