I know 4 Kempf families, who emigrated in 1852 together with 458 persons from Viernheim in Hessen-Darmstadt to New York. They arrived New York in August with the ships Messenger of Salem, Vandalia and Barque Laurens. I think this families lived the first time in New York. Do you know this families? The head of one of this families is Peter Kempf (born 2.1.1805) and his wife Eva, born Schmitt.
