Jothar, you are right, but I know an Elyokum and as he is a BT I questioned whether he had his name right. He insisted it was his grandfather’s name, spelled with a vov. However, I think it still is erroneous and that his family may not have been too learned, or, more likely, his ggf might already have left Yiddishkeit and hardly knew or cared whether his son’s shem beYisroel was correctly spelled.
