majority of the historians, including mór wertner, zoltán kordé and attila zsoldos considered, bogomer (or bohumír) was born into the "gens" (clan) ludány, which owned landed properties primarily in nyitra county. according to the "gesta hunnorum et hungarorum" written by chronicler simon of kéza, the ludány kindred originated from bohemia, which claim is strengthened by the frequency of slavic-origin personal names within the kinship. bogomer was one of the two known sons of szoboszló i (or sobéslav), who served as "ispán" of sempte ispánate (today šintava, slovakia) in the territory of nyitra county in 1221. his brother was wytk i, ancestor of the ludányi family. bogomer had at least two sons from his unidentified marriage: peter i (fl. 1277–97) and szoboszló ii (fl. 1283–95). based on a brief comment by a charter issued in 1296, regarding peter (who became a "familiaris" of the powerful local lord matthew csák by then), it is presumable that paska, bishop of nyitra was also bogomer's son. through szoboszló ii, bogomer was the forefather of the emőkei and szobonya noble families.
