I don't know when the they arrived in the USA but have just found that Rudolph the father of William was Naturalized on April 19, 1859 along with Charles A. in Boston, Mass. and was a resident of Wrentham at the time. Rudolph was born Jan. 14, 1832 in Germany. Charles was born April 6, 1827 in Germany. Does anyone out there have information on this family. William was the son of Rudolph and born in this country.
