Mencl from Ohio/Nebraska

I’m looking for the Mencl family that settled in Ohio and Nebraska. Two brothers came over to America, John Mencl in 1906 and went to Crab Orchard, Nebraska and the other, Joseph Mencl in 1912 settled in Cleveland, Ohio. Both came from Ludinor Velika, Bohemia.

I would also like to know if there is any connection to the large Mencl family that settled in Chicago, Illinois around 1850/1860.
