I have a great grandaunt, Hanne Dorothee Wilhelmine Justine Ahrens who was born in Hehlen Germany, a village on the Weser River, on September 26, 1818. When my great grandfather, August Friedrich Wilhelm Ahrens, came to the USA in 1848, he came to visit a relative, Mrs. Ed Ahlswede, in Rockwood, WI. He was born in 1828, so Hanne would have been his older sibling by 10 years. When August was married in 1855 one of the witnesses was Ludwig Ahlswede (Ed Ahlswede?). I knew that we were related to the Ahlswedes and this makes the relationship clearer. Ludwig was his brother-in-law!
