My first husbands family were Demzien's. All are buried in the mostly in St.Johns cemetary, Laporte, IN. They were all MIssouri synod Lutherans. According to the family the first Demzien's came to Laporte from Germany before the civil war. I have a limited history on the family from my father-in-laws brother (both now deceased). If you are interested I will e-mail what I have.
