Hello, I have found the reference to the name Vytopil through Google. My Grandfather (my mother's father) was named Franz Xaver Vytopil and his family came from the Czech Republic (which then still was part of the Austro-Hungarian Monarchy).
As far as I know, he and his wife, who died only last year, were the last persons with this surname in Austria.
I started looking into the roots of his family tree only lately.
If this might be of any help...
