My gr-grandfather was Franz Arnold Theodor Wieman(n) born in 1836 to Franz Georg Wieman and Bernadine Catherine Theresia Terheyden Wieman in Osnabruck. Arnold and his brother William Joseph emigrated to America in June of 1866. The next year their brother Leopold joined them. Arnold and William settled in Pittsburgh,PA and Leopold in Baltimore MD. Leopold traveled back to Osnabruck several times and the family home was located on 53 Hasestrasse in Osnabruck. It is now a restaurant. Wondering how many Wiemann families lived in Osnabruck?
