Boys' Names: O-R
Here are all the names from the lists on this site alphabetized into one. The "category" tells what type of name it is. Check that individual page for more information on what it means. Note: I have put pretty much all the place names and surnames into both the Girls and Boys categories since they are pretty much gender-free. NOTE: "Other Forms" names in italics represent names that were traditionally used to "translate" the Irish names. They are only related by tradition and sound, not by etymology.
