The present article follows upon the work of Jan Miroslav Kvet and Jiri Musil concerning ancestors of the Czech composer Antonin Dvorak and corrects some mistaken conclusions they reached. Attention is devoted primarily to ancestors of Dvorak's grandfather on his mother's side, Josef Zdenek, whose parents - and therefore other ancestors as well - were wrongly identified by the above-mentioned researchers. It turns out that some of Dvorak's ancestors came from Bystrice (Wistritz), a village in Northern Bohemia near Teplice which at that time had mainly a German population. This is where the earliest determined ancestors of Antonin Dvorak lived, in the 17th century. Appended to the article is a list of all known ancestors of Dvorak's grandfather Josef Zdenek giving dates of births, deaths, and marriages.
