I have tried in the past to see if I could tie in to Isaac White and have been unable to. My James White married Hannah Yardley. I know her parents (Richard), grandparents (Richard), but not his. We believe it was John White who had several sons, but have not been able to find positive proof. John White lived in Lower Makefield Township (near Yardley). Supposedly James died in 1812, probably buried in the Slate Hill Cemetery (again no proof, but one of his daughters, Lucilla White Cook and her children are buried there). His sons George and Samuel moved to Ohio about 1830. Had sisters one who married Mitchell lived in Miami Co Ohio. One married a Scott. Lived in Champaign Co. Ohio. Hannah moved to Miami Co Ohio a few years after her sons and died just a few years later..in the 1830s. Mike Daley
