This is obviously a phonetic variation of the ancient Slavic disyllabic name Chьstiborъ. In ancient Latin-script documents of the Hungarian language from Transcarpathia, this anthroponym can serve as a surname. For example, in 1641, it was recorded as Csibor Laszlo (read as Chibor Vasyl) - village of Romochevitsa (Hod Okm 87).
