In 2010, 6 American boys were given the name Eleftherios.
No, not a Tolkien character — the father of modern Greece! Eleftherios Venizelos, a revolutionary and politician in the early 20th century, is widely credited with modernizing the Greek state. Though not uncontroversial, Venizelos obviously has some fans in the US. Either that or there really is an obscure Tolkien character out there.
