My gg-grandfather Gottlieb Messner born 1847 in or near Trossingen Germany came by ship to the United States with the following Messner's. Christian born 1837, Friederich born 1845, John born 1840 and Matthias born 1844. They all came on the same ship at the same time and lived in the same town, Trossingen, Germany. Are they brothers ? Are they related at all ? please contact me if anybody has information on any of them.
