Jan spoke of interdenominational marriages whose roots are the passage to America, one of which was between a Reformed minister and a Brethren woman. Unless you are talking about the ship Allen of 1729, that Brethren woman would not have been Brethren on the boat. Only a handful of Brethren were Brethren when they immigrated, and that was the Allen and an earlier unknown vessel about a decade earlier. Most Brethren became converted once they were in America. However, your general point is correct, that there were plenty of interdenominational marriages that have connections that begin on the boat to America. There are numerous cases of marriages between Reformed and Mennonite members. Bill Thomas
