Maureen, This file [url below] may have the answer you seek.I know this person is related to my friend, Michael B.I found this site while looking for his family. Mike said this is one of his cousins. Carl's father, William, collected the information, but it is not sourced in the file. You can probably get Carl to put you in touch with William.
I know that Michael is descended from Carl Bussjaeger [b. Nov 1850] and Josephine Habert.I got that far back by myself using online records. I did find Carl in MN, later in St. Joseph, MO.According to William Bussjaeger, Carl was a brother of Ulrich, and a *whole bunch* of others!
