To answer my own question, Prall Dilts is the son of Emanuel Lemuel Dilts (1847-1921) and Elizabeth Wolverton (died in 1881), who were married in 1867. Emanuel married a second time in 1894 to Sarah C. Burkett (1864-1924). Emanuel is the son of Asher Hill Dilts (1820-1893) and Agnes Moore Case (1829-1915), who were married Dec. 15, 1845. I can trace the Case's back a couple more generations, but I've hit a wall on the Dilts side. Anyone have any information on this guy, my great great great grandfather? I think he was from Rariton NJ.
