I believe that we are looking for the same person. I am looking for information on the family of my great-grandfather, Frederick Baas who I believe emigrated from Badan in the 1850s. He fought in the Civil War and was with General Sherman on his march to the sea. He spent much of his life in Chicago after arriving in the United States, but appeared to have moved around somewhat also. I have pictures and am willing to share. My Frederick Baas also had brothers, Michael and George.
