Looking for descendents of Adolph Eberhart of Fayette County, PA that were involved in the glass industry. Adolph's son William operated a glass plant in Belle Vernon, PA about 1850. His daughter married Noah W. Speer/s, Jr of BV. Noah and ELizabeth lived in Cincinnati until a fire destroyed the warehouse. They moved to Memphis where Elizabeth died of Yellow Fever about 1870's. Noah died about 1910. His son Noah W. died about 1928. Some of their children were seen near Colorado Springs, CO. and may have died in Manitou(?) Colorado in Crystral Springs Cemetery(?).
