Could stretch it to a middle name...and Robert William Feller would be a great one. Who wouldn't love Feller? Tremendous heat, WWII vet, and very kind man for the rest of his life.
James Emory Foxx....so he tossed back a few drinks
. Your son may find Foxx's on the field exploits very appealing, massive home runs...and has two good nicknames he could take from him, "beast' or 'Double X". Plus if Foxx had the luxury of all the short RF porches around the league back then(compared to the longer left field porches), he would have had the single season home run record.
