From the experts:
Eleanor is back, Nora is back, and soon Eleanora will be too. Off the charts since the 1930s, this elaboration of the classic Eleanor was in common use for decades before falling from favor. Spelling Eleonora adds yet another syllable to make the pronunciation el-LAY-oh-nor-a, and you can try to instruct people to say Eleanora that way too, but most will pronounce it like Eleanor with an a at the end and that's just fine. That final vowel gives a serious, stately name a little flip at the end, making it more distinctive and modern if not right for every taste.
