James as a New Testament name is a myth because the Greek text has Iakob, as close as Greek can come to the Hebrew name Yaakov because there is no letter v in Greek so early translators used b instead. The translation of Iakob to James is the only name in Scripture that is translated, not transliterated. English did not even become a language until several centuries after the New Testament was written, so it could not have been known to any new Testament author. English and English bibles translated into other languages are the only ones with a translated name, so why is that? The letter J came into the English language in the 1500s. King James is the one who ordered the 1611 King James translation and paid the translators, but some earlier English translations also have James. Since we do not have original manuscripts to check we cannot be certain that what we have was changed to James at a later time. If the name James is not from the King James of KJV fame, then it must be some earlier James. The Latin Vulgate was used for the earliest English translations and that too has Iacob instead of Jakob. The book of Jacob is in the One New Man Bible and in other foreign language bibles not translated from English.
