Jerome English: ostensibly from the medieval given name of the same spelling (OF Jéròme, from Gk Hieronymous, composed of the elements hieros sacred + onyma name), which achieved some popularity in France and elsewhere, being given in honor of St. Jerome (347-420), who created the Vulgate, the standard Latin version of the Bible, working partly from earlier Latin texts and partly from the original Hebrew, Aramic, and Geek.  However, this was a rather rare given name in England in the Middle Ages; the comparative frequency of the surname is explained by the fact that it has also absorbed a Norman personal name, Gerram, composed of the Gmc elements geri, gari spear + hraban raven.
