Okay, I’ve been having too much fun with this (as in spending more time than I ought :)) Here’s what I have so far:
[name]LEO[/name]:
[name]Elliot[/name]
[name]Julio[/name]
[name]Leander[/name] (I know you prefer [name]Evander[/name], but [name]Leander[/name] is still cool and could get you to [name]Leo[/name])
[name]Leonas[/name]
[name]Leonid[/name]
[name]Leontes[/name]
Leor (the three above are variations of the [name]Leo[/name]=lion names. Leor is Hebrew, from a root meaning “light.”)
[name]Napoleon[/name] (I do not imagine you want to name your son after [name]Napoleon[/name] Bonaparte, but after I whimsically stuck Bonaparte in the “[name]Bo[/name]” name list, I couldn’t resist putting [name]Napoleon[/name] with the “[name]Leo[/name]” names.)
[name]KAI[/name]/[name]CAI[/name]:
Caiaphas (Cool name, uncool namesake. He was the Jewish high priest who presided over part of [name]Jesus[/name]’ pre-crucifixion trial.)
[name]Carlyle[/name]/[name]Carlisle[/name]
[name]Kyle[/name]
[name]Michael[/name]/[name]Mikhail[/name]
[name]Mordecai[/name]
[name]FINN[/name]:
[name]Finbar[/name]
[name]Fingal[/name]
[name]Fintan[/name] (all three Irish)
[name]Phineas[/name]
And just for fun, some Elvish names from J.R.R. Tolkien’s mythology. I realized, when thinking about [name]Finn[/name], that the “fin” element was used a good deal by the Elves, particularly those of the First Age:
Curufin
Finarfin
Finrod
Finwё (prn. [name]FIN[/name]-way)
Glorfindel
[name]BO[/name]/[name]BEAU[/name]:
Beaulieu (prn. BEW-ley, this is an English surname and place name derived from the French beau lieu, “beautiful place.” Unfortunately, the first thing I found when I Googled “Beaulieu” was Beaulieu carpet. Didn’t know such a thing existed…)
Beaumont (“beautiful mountain”)
[name]Beauregard[/name] (We actually have a young councilman in our neighboring town named [name]Beauregard[/name], nn [name]Beau[/name].)
[name]Boaz[/name]
Bodil (Norwegian, “commanding.”)
[name]Bogdan[/name]/[name]Bohdan[/name]
Bonaparte (!)
Bonar (Scottish, from Old French, “gentle.” I have seen it as a surname.)
[name]Bowman[/name]/[name]Boman[/name] ([name]Bowman[/name] is an English word name, “bowman”; [name]Boman[/name] is Persian (?), meaning “great mind.” Rereading your original post, I see you already have Boman on your list.)
As always, best wishes, and thanks for sharing the continuing challenge! Maybe it’ll be a girl, and all your troubles will be over
