I've heard that my Ollingers may have come the Prussia/Germany area prior to 1800. My gr-gr grandfather William Ollinger was born in 1831 in Echternach Luxembourg. His father was Heinrich B.1804 - it says in Echternach as well. And his father George B. about 1758..maybe in Germany.
Does any of this information sound familar to you? Any leads would be apprciated.
