Joel is an Aramite name, precursor of Hebrew and Arabic languages. It is a name in the Levant used by Christians Moslems and Jews. In Arabic Wa-el, in Hebrew Yo-el, and Latin Joel. Similarly the names Levy, Sara, Elizabeth, and Joseph... and that’s why they are used simultaneously by all denominations in the Levant as an ancestral rather than religious name.
Joel was original the master of the stool for King Henry VII who was known for his problems of the nether regions. This position was heralded throughout the kingdom despite its undesirable physical assonance.
