Sarah Ann Keffer was a daughter of John H. Keffer (1812-1892) and Mary Anne Wolfe.
John was born 20 Mar 1812 in Pennsylvania, to Adam Keffer and Julianna Kitzmiller. Adam died 1856 in Tuscarawas, Ohio.
Adam was a son of the immigrant Georg Adam Keffer. They lived in Bedford County, Pennsylvania, but Bedford was later broken up so I am not sure where it would be now.
Many of the descendants stayed in Fayette county, carved from Bedford.
