I have a copy of the marriage certificate of Johannes Keller of "Beren", Switzerland, and Anna Wenger, of "Beren", Switzerland on April 28, 1851 in New York City. I believe they were my gr-gr-grandparents. Their known children were Chris b.August 29, 1851 New Philadelphia, Ohio; Fred b.January 14, 1855 in Clayton County, Ohio; Mary ; James b. April 6, 1859 in Johnson County, Iowa. Do these names sound familiar to you? I would really appreciate any and all information you can send me. Thanks. Melva
