Parents were Anna Duren Bowar (1876-1960) and Frank Peter Bowar (1874-1943)
The 14 children in that family were:
Michael P. Bowar (born 4/30/1897)
Sybilla A. Bowar Braun Church (born 10/28/1898)
Herman W. "Pat" Bowar (born 4/24/1900)
Leo C. Bowar (born 12/28/1901)
Aloysius J. Bowar (born 7/12/1903)
Edward J. Bowar (born 1/20/1905)
Sylvester J. Bowar (born 5/5/1906)
Agnes Bowar Giesen Fiegen (born 1/20/1908)
Theresa J. Bowar Fiegen (born 5/5/1910)
Henry Bowar (born 1912)
Francis H. "Bub" Bowar (born 1/27/1914)
Eleanore Bowar Loughlin (born 1/1/1917)
Herbert L. Bowar (born 11/3/1918)
William C. Bowar (born 10/31/1921)
The first 13 were born in Wisconsin. Not sure where the last child was born, probably South Dakota.
The family moved from Cazenovia, Westford Township, Richland County, Wisconsin, to Orient, Faulk County, South Dakota, in October 1919.
I'm hoping someone will be able to identify each person on the picture.
