I'm a Barteau in Missouri! My dad and my grandfather were both named Howard, one, Howard B, the other Howard L. Lived in St. Ann, a suburb of St. Louis. Grandpa had 13 bothers and sisters, grew up in Florissant, MO. I had heard that our name had an X at the end of it, many years ago, and also had heard that one of my relatives had been a Frenchman and was part of the Lewis & Clark expedition. Would love to know more about any history and ancestry work that's been done to date.
