Can some kind soul please direct me how to locate birth or census information on Heinrich SCHRÖTKE, born 1845 in Kingdom of Hanover. He may have had a brother Johan but I know nothing of his parents or other possible siblings. He was Lutheran by religion. I believe he was a laborer but he may have had saloon keeper in his background as he took up that profession in Minnesota. He immigrated in 1866, departing from Hamburg, on Palmerston Ship, arriving on 20 Oct 1866 to New York.
