I'm looking for the parents and siblings of my grandfather Frank John Zavoral, born 28 Sep 1878 in Radnice, Bohemia. He immigrated to the US in 1910 or 1911 and married my grandmother Rose Svoboda in Chicago in 1919. He died in 1945 when I was a baby and so did my father, Frank John Zavoral Jr. His family in the US (my aunts and uncle) knew very little about his family in Bohemia.... he wouldn't talk about them. Since he arrived in the US a full grown man, we don't think he was accompanied by parents or any other relations, but we don't know. Any help finding anything about him would be truly appreciated. I'd also like to know the meaning of the name "Zavoral" if there is one. There are many Zavorals in the midwestern US...others in Chicago IL where he met my grandmother, many in Minnesota, Nebraska and Iowa, but I have no idea if any of them were related to me.
