Do not be fooled by dates such as those, as you will sometimes read that Azizius / Aristobulus died in 54, whereas in 57 he and Salome issued a coin with both their portraits on it, and he didn't die until about 62/63. James died within a few short years or less of then, but that doesn't mean he isn't Soemus. Many historians were off by a decade or two, and almost everything you think happened (eg. New Testament) in the second quarter of the 1st century actually happened in the 3rd.
