Have you found out any more about your great grandfather Jonas Scartner? Did your Scartner's originally come from Austria? I have traced my husband's ancestors to the father of Friedrich Schartner, (born about 1800) whose father was an organist in the Lutheran Church in Koenigsberg, Prussia about the middle 1700's. But I'm stuck there. I have done a genealogy DNA for my father in law (Abraham Schartner. We are looking for more Schartners to see how close they could be related. Are you interested in this?
