My Muster/Kunzler(Koernsler)ggrandparents, from Basel (we think), were, according to a newspaper article about them, married "right before" they sailed from Bremen for New York in 1864. Would either a church or the civil authorities in Bremen have married them--if they were Swiss citizens? Someone has suggested that it would have been very difficult for them to be married in Bremen--and that, perhaps, they were married in Switzerland and left immediately for Bremen. But if they were married in Bremen, would there be a civil record? Thanks for any help. Jo
