I am trying to research my family's surname. My great-grandfather, John Lewis Abele was born May 2, 1843 in Wittenberg, Germany. He married Marguerithe (sp?) Filbert who was born Jan. 25, 1845 at Leiern by the Mein River on Sept. 27, 1874 in Iowa. We cannot go back any further, but we know there are brothers who stayed in Germany and probably later emigrated to the U.S. Any info would be greatly appreciated!
