I'm the descendant of Fred Birr and Minnie Petrofska who moved to a farm in the town of Hixon around 1912 from Chicago. Other relatives may be in Withee area.
I believe Fred was the only child of Johana.
Fred (b. 17 May 1859)and Minnie (Hermenia?) had 4 children:
Edwin Herman Birr (b. 22 Apr 1885)
Frederick Birr (b. 10 Mar 1887)
Otto Birr (b. 2 Jan 1890)
Ella Birr (b. 25 Jun 1895, d. Feb 1983) - Married Harold Heideman
