Please help with names!

I’ve got a daughter called Truly and five weeks away from giving birth with no name for our boy! I want it to go with Truly and not purposely looking for an ‘out there’ name but just want a lovely but cool sounding name. Partner currently likes Monty which I think is nice but don’t feel like it is ‘the one’ I’ve flirted with names like Sonny, Rory, Ernie and Ari so I think I like the two syllable ending in that ee sound but please someone help!
