Just gonna roll some names off the top of my head to keep you on your toes!
Alfie,
Archie/Archer,
Dorrian/Darrion,
Treyton (think it goes well with you little boy's name),
Reily (just because it's my fave boys name!),
Adrian (think it's less popular these days),
Alban,
Alessandro (italian form of Alexander),
Alessio (used to work with someone with this name,loved it),
Ariston (greek for the best!!),
Tarkan (another random one I like).
