Predslav
Predslav is an almost unknown son of Svatopluk, the most important ruler of Moravia.
Generally, two sons of Svatopluk are known: Mojmír II and Svatopluk II. However, the famous legend of Svatopluk's twigs, written by the Byzantine emperor Constantine Porphyrogenitos around the 10th century, mentions three sons. It is supposed that the name of the third son could be Predslav. This name is mentioned in the list of pilgrims scribbled in the 9th century on the margins of a Gospel book in Cividale del Friuli, together with the names of Svatopluk and his wife.
Daniel Rapant suggested that Predslav's name may have given the name to the Slovak capitol: i.e., Bratislava.
