Andrew STOLLAR Spouse: Rosannah ELEY Marriage: Abt. 1793, Schuylkell, Chester, Pennsylvania Source: none

There is a Schuylkill Township and an historic Schuylkill Post Office in Chester Co., PA.  This location makes far more sense than Schuylkill Co., which wasn't formed until 1818, both as a marriage location and as Rosanna's birthplace.  Too bad there's no source for this record.
