I am looking for information regarding the family of Charles Balthazar Braun/Brown (b. 7-8-1845, Bavaria) who immigrated to the U.S. from Germany in 1867. Supposedly, Balthazar's parents were Andreas Braun and Dorothea Lauth. He was the 4th of 7 children. He married Julia O'Neal (b. 1855) in 1874 in Benton Co. According to the 1900 Benton County Census they had 10 children. The 7 youngest are as follows:

William
Anna Cecilia (m. Henry Haas 1907)
Thomas
Joseph
Rose
Elizabeth (m. Archibald McKean 1919)
Andy

I would like to find the identities of the 3 oldest children and the fate of the family. Balthazar's sister Apollonia Braun Keller was my 3rd great-grandmother.

All help is greatly appreciated.
