Pat, I have one Crabill who married into my family and I'm curious about him, not much seems to be available. He is Christian Grabill who died abt. 1805 in Shenandoah County, VA. He was married to Freany Burner, who was the daughter of Erhardt and Anna Burner.
Online around 2000 I found information that this Christian Graybill was b. abt 1739,son of Ulrich Graybill b. 5-15-1705. The children of Christian and Freany were supposed to be: Abraham, Daniel, Jacob, Barbara, Mary, Henry, Christina, and Christian. Birth years are est. from 1769 for Abraham to 1786 for Christian. I don't have any proof of the above except a mention of Freany Greable in an indenture by her parents in 1793.
