Dude, I can't possibly choose names for other people's kids! It's too personal an act.. and as such must be made solely on the whim of the choser's fancy.
It depends what exactly they're after. If one wants a name that is normal but under-used you could choose from a range of names, from Alec to Jake, Kenan to Walker, Jefferson to Lawrence - depending on the length, characters and sounds they prefer.
*throws some more names about*
Heath, Damien, Blaine, Elliot, Lukas, Quinten, Kingsley, Finlay, Malachi, Riley, Lyon, Parker, Nathaniel, Sawyer, Pierce, Xavier, Uri, Farrar, Dixon, Irving, Orson, Zander, Zane, Zave, Zechariah, Tiernan, Tobias, Hadden, Dane, Yves, Garrett, Harrison, Jude, Clark, Eli, Philip, Noel, Ramsey, Kendall, Rowan, Sebastian...
I could be here all day! The above suggestions are guys names I quite like for their strength and uncommoness, 70% of them are the one-of-a-kind names of people I know (I seem to attract oddly named persons...e.g. Rafael, Fabian, Mena are all ordinary Australian guys with eccentric sounding titles
)
