Vasek, Zak/Jak

I am looking for Anton Vasek, born March 3rd, 1855 in Bohemia, possibly Prague, and his wife, Victoria Josephine Jak, or Zak, born August 27th, 1852. They had 9 ch, Joseph, Anton, Louise (Dale), James, William, Emma (Stengle), Rose, Bessie (Calhoun) and Louis. The family came to America around 1883, and set first in MN, later OK. The ch moved to various parts around the US, any info on anyone would be very helpful.
