I am trying to locate information on the families of Katerina "Catherine" Bouzek b. about 1874 in Bohemia and who married Jan "John" Vavra b. about 1867 in Bohemia. They married in about 1894 in Bohemia and had at least two children there before the family immigrated to the United States in Aug of 1899 -they arrived through Baltimore (on the boat Dresden) and are listed as having come from Zic and planning to go to Minnesota to my great great grandfather and great great grandmother (Jacob Senkyr b. 1846 in Bohemia and married to Frantiska Vavra b. 1854 in Bohemia). I believe that this is a brother or other close relation to my Frantiska Vavra.
Later (1900 Federal Census) I find this Katerina and Jan (and children) living in Cedar Lake Minnesota along with another sister to Jan (Anna Vavra b. 1873 in Bohemia and married to Thomas Mikolasek b. 1872 in Bohemia -married in Bohemia and immigrated also in 1899).
The children of Katerina and Jan are Jan (John), Frantisk (Frank), Mary, Josephine, Agnes, Rosey, Vaclav (James).
The children of Anna and Thomas are John, Mary, Frank, Edward, Thomas, Joseph.
The children of Frantiska and Jacob are Frank, Mariam, Christina, Joseph William, John Martin, Jacob, Charles, William Rudolph, Michael, and Agnes.
I am hoping to find out more information about Katerina, Jan, Anna, or Thomas in hopes of locating the parents, relatives, village, or area that my Frantiska (and likely Jacob also) is likely to have come from in Bohemia.
Frantiska and Jacob have been a brick wall for me for a very long time. Any help that anybody can provide is greatly appreciated.
