Searching for Ida Tetzlaff Arndt, born 9/10/1861 in Oldam(Altdamm) Pommerania, Prussia (later Germany). Altdamm is now known as Dabie, Szczedin, Poland. Father's name was William. Married Wilhelm August Karl Arndt(born 5/24/1862) and lived in Oldam until emigrating to the U.S. in 1894. Children were Bruno Karl August Arndt born 9/9/1888 in Oldam, Minnie(Wilhelmena?) born 5/2/1892 in Oldam, William Arndt born 8/20/1896 in Richmond, MI, and Annie born 10/16/1898 in Milwaukee, WI. Someone in the Tetzlaff or Arndt families wore a spiked hat in the Prussian army. Ida had a sister who supposedly lived on Long Island, NY. The sister had two sons Carl and William. The other story is that Carl and William were Tetzlaffs and lived on Long Island. William was chairman of the board of New York Life Ins Co. Carl was an aeronautical engineer. Any suggestions or clues in finding this family would be appreciated.
