Vowel-Names for Boys

It occurred to me the other day that I do a lot of 'names by construction' posts for girls, but not really many for boys. So then I had to think of what I could do--besides the overplayed -aidens, and surname-y -sons & -tons, boys' names don't really have a lot of distinct patterns.
However, while vowel-y names for girls are in abundance, there aren't a lot for boys....
