There's also no documented close lineal connection between John C. Dvorak and August Dvorak, any more than his birthplace being Los Angeles. Both of which are blindly-repeated, unsourced (and untrue) Wikipedia inventions.
"I'm told there is a relationship, but I can't prove it."
John knows who his uncles are. His father is Walter Charles Dvorak born in Minneapolis to John Steve Dvorak (also born in Minneapolis). August Dvorak and all of his siblings (none of them Walter) were all born in McLeod County to IMMIGRANT Joseph Dvorak. If there's a connection it goes back to Bohemia.
