Don't know if we have a connection by my Mrkvickas came from Bohemia. I have an Anton Mrkvicka, married Maria Yanovic and they resided in Haugen, Wisconsin.
He died Oct 12, 1929 and is buried in Haugen, Wisconsin.
Maria died June ll, 1932 but when I tried to get a copy of her death cert.,Vital Records did not have it so I don't know if she died in another State.
Their children were: Barbra, born in 1886 and she married a Mr. Dobromysl and then Joseph Jilek Sr. and Barbra died Mar 8, 1924 of TB. The second child was Antonia, born Aug 6, 1894 in Prague and she married Charles Martin Hrdlicka on June 29, 1915 and died July 6, 1978. She is buried in St. Albert, Alberta, Canada. Antonia is my husband's great grandmother.
Since you mentioned Wisconsin and Anton, I thought I would see if we have a connection.
Sincerely, Theresa Kowall
