The paper deals with anoikonyms derived from personal names by a suffix (the structure types Bartoš + -ka, Bartoš + -ovka, Bartoš + -ovec, Bartoš + -ovice etc.). The first part of the paper presents their onomastic characteristics: it pays attention to their word-forming structure, motivation, frequency, eventually productivity of certain structure types; also information on their geographic distribution is added. Selectively also those anoikonyms are presented which are hard to explain. The second part compares the onymic maps (maps of some structure types) with dialect maps (especially the maps of the so called bundles of isoglosses contained in the Czech Linguistic Atlas). Mutual interconnections of the onymic and dialect areas are explored.
