Yes, Steinfeld in Mecklenburg-Schwerin. Charles Steinfeld (1808-1890) immigrated to the United States sometime before 1846. I have no information on his family in Germany. He settled in Marion County, Ohio. He married, first, Mary Ann Carpenter (1823-1847), in 1846 in Marion County, and, second, Lamira Page McWherter, in 1849 in Marion County, Ohio.
