My ggrandfather, Louis Oster, arrived in Woodford County sometime before 1857 from Landroff, Lorraine, France which is south east of Metz. He married Susan nee Harmon Mathis in Nov of 1857 in Spring Bay. They are listed on the Spring Bay 1860 census with his name misspelled as Oyster. I haven't yet found when he entered the country. In about 1869 they moved to Iroquois County.
