I am researching WUNDERLE. Margaret, b. 1815?, Baden?; supposedly immigrated with her parents to St. Louis in 1830; then to Dubuque, IA, in 1832. Married Xavier REINFRIED. The first record I have of Margaret Xavier REINRIED is the baptism record of their daughter, Margaret, 1835 in Pittsburgh. They settled in Dubuque, IA, and had many more children.
