All of the boys names that we seem to like end in an “n”. Our last name also ends in an “n”…think [name]Anderson[/name], [name]Thompson[/name] etc. [name]Do[/name] any of these names work or is it too much of the same sound? Help!
I think all your choices work just fine. Because the repeating sound is not in a stressed syllable, you don’t really notice that it’s there until someone points it out. People would pronounce the names [name]RYan[/name] [name]THOMPson[/name], and don’t really think about the ends of the words. 
I agree with pp. Unlike some of the trendier names that end in “n” these aren’t rhyme-y.
