I found a little more information from their death certificates and USA census. For John on his Minneapolis, Hennepin County, Minnesota death certificate it gives name as John (Boch) Buck, date of birth Nov. 23, 1857, birth place Czecho-Slovakia, fathers name Andrew Buch birth Czecho-Slovakia, information is from his wife Mary T. Konieczny. On the 1930 Census Minneapolis, Hennepin County, Minnesota it gives mothers tongue as Slovak. His 1900 &1905 Census gives birth place as Austria. His 1910 gives birth place as Austri-Bohemia, and the 1930 gives birth place as Czehoslovakia. On his 1900 census it said he is Naturalized but I can not find it
For his wife Mary T. Konieczny, Minnesota Death record info given from daughter, Mary's birth April 22, 1863 in Czechoslovkia. Father John Konieczny, mother Mary Petrichko both born in Czechoslovakia. Mary T. Konieczny 1930 census gives mothers tongue as Slovak. 1900&1905 Census of Minneapolis, Hennepin County, Minnesota gives Austria as birth. The 1910 Census gives Austria-Bohemai as place of birth and the 1930 census gives place of birth as Czehoslovakia. They were Catholic. Hope this will help to find some info on them before they came to the US. Any help is appreciated.
