I have a Peter Marti born 1864 Kallnach, Bern, Switzerland. Died in 1900 in Canton, OH. Canton is neighbor to Warren, OH. Peter married Cecelia Krippa/Crippa. They had six children: William Peter (1888), Flora Cecelia (1889), Sylvia (1891), Leon (1893), Fred (1895) and Carl (1898). The first two were born in Switzerland and the last four in Canton, so I guess they came to the US in 1890. The family lived for a time in Canton, OH, then later settled in Ambridge, PA.
