I don’t know anyone whose name is Eugenelio. I know a lot of Eugenes tho, it’s a common name

Eugenelio像一个拉丁名，应该和Eugene(英语名)是一个。通常英语名和汉语名不一样，英语名很讲流行。最后选当下流行的。太生冷的的确会让人有联想

可能会让人觉得你是一个racist,因为eugenics是德国纳粹奉行的思想，而且起这个名字有点像俄国人....

你喜欢的话，也可以去美国参军啊。

前面一个更像是意大利语或西班牙语来的，后面一个是比较少用但也属于常见的名字。

"Eugene has had a long history of popularity, as a Top 50 name from 1880 to the 1940s. In fact, it has never been out of the Top 1000, making it a classic that's still given to hundreds of boys each year."

Generally speaking, common names, like Jim and Eric, are preferred bc people know how to pronounce.
