I am tracking a Luxembourg immigrant family who lived in Lafayette between the years 1855-1865. The father was Joseph SCHNEIDER, and his wife was Margaretha SEINERT. Their oldest known child was a son named Joseph or George, born in about 1855 in Lafayette. The family was Catholic. They had four more known children while living in Lafayette: Louisa, John, Herman and Charles. In about 1865 the family moved west to Minnesota.
I presume this couple married in the USA, possibly in Indiana. Where would I go to find a church record? When did Indiana civil records begin? Was there an Indiana state census in 1855? How about a census in 1865?
