Jacox
Jacox is a family name of English origin.
Jacox is an ancient Anglo-Saxon name derived from the baptismal name for the "Son of John" (John the Apostle). It was originally derived from the Hebrew given name Yohanan, meaning "Jehovah has favored me with a son." Jack was used as a nickname for John and the suffix -cock was added at the end to signify youthfulness. Jack-cock was soon abbreviated to Jacock and over time underwent many spelling variations including Jeacock, Jeacocks, Jecock, Jacocke, Jacock, Jacocks, Jaycocke, Jaycocks, Jeacox, Jacox, Jaycox, Jacok, Jecok, Jecockes and Jecockes.
