Which out of these three do you prefer:
[name_m]Kellan[/name_m]- “Slender”
[name_m]Callan[/name_m]- “People Of [name_f]Victory[/name_f]”
[name_m]Callum[/name_m]- “[name_u]Dove[/name_u]”
I like both [name_m]Kellan[/name_m] & [name_m]Callum[/name_m]. I would happily use [name_m]Callum[/name_m] myself if it wasn’t already in use in the family.
[name_m]Callum[/name_m] is one of my favorite boys’ names and it’s my favorite of these three, so that’s my pick. “[name_u]Dove[/name_u]” is a lovely, peaceful meaning and [name_u]Cal[/name_u] is a great nickname.
Meaning wise [name_m]Callum[/name_m], but preference wise [name_m]Kellan[/name_m] 
[name_m]Callum[/name_m] for its meaning. But I like all 3 names.
[name_m]Callum[/name_m] is gorgeous! It would be on my list if I didn’t already know a few Callums.
All three are lovely, but my personal preference goes to [name_m]Kellan[/name_m]
