Christian Tarr (1765-1833) was a Congressman from Pennsylvania from 1817 to 1821. Does anyone know if any libraries or historical societies in southwestern PA have any of his papers or additional information about him? The United States Congress has online information about former members and they have a short biographical sketch of him and I'd like to learn more. The Congressional website says that he died in Washington Township in Fayette County, PA, and interment in the Methodist Graveyard, Brownsville, Pa. Thanks.
