Mark, I have some information that might help you. My Schneiders emigrated from Luxembourg to Wisconsin in 1954. This is documented by the birth of a child, Adam Schneider in July 1854. He was born at sea and was baptized in Chicago at St Michael's Catholic Church. His family (and many aunts and uncles) settled in Cedarburg, Town of Holland, Sheboygan Co., Wisc. You can find his families in the 1860 Census in that area.
If you would like more information, just let me know
