Hi
Nikolaus Wambach in my family tree was born on March 26, 1826 at Luxemborg, Germany and shows up in Canada in 1861. He then emmigrated to Georgetown, Clay County, Minnesota after 1871 and shows up in the US Census in 1880. His wife's name was Katherin Tiber Leitzen, 1832-1914. They had 13 children. I have quite an extensive descendant chart of Nickolaus and cannot find the Nickolas Wambach you refer to in my charts. I am a descendant of the Nickolaus Wambach in Clay County. Many of his descendants stayed in this area. If I can help in any other way, please let me know.
