Bill,
I thought I'd throw this into the mix and see what you might think. 1810 tax records of Fairfield County, OH has an Abraham Harsbarger. Shenandoah County has a listing for an Abraham Hashberger in the 1810 census. There are 2 females and one male under ten along with one male and one female in the 25-44 age group. This could be the Abraham that married Catherine Rinehart, daughter of Lewis. Lewis Rinehart Sr is enumerated two lines above Abraham and Lewis Jr fives lines above his father. The ages would give the impression that this couple was married about 1800.
