I voted for [name_m]Owen[/name_m] as he really fits well stylistically in my opinion. Such a handsome name too.
I’ve been seeing your posts and keep being reminded of an acquaintance of mine. His name is [name_m]Dean[/name_m] [name_m]Owen[/name_m] (FN MN). Thought I’d throw it out there for you! The flow isn’t what one immediately thinks is perfect, but it’s really grown on me!
Also, I’m sure you’ve considered all the options, but just wondering if you’ve ever considered using just [name_m]Theo[/name_m] as the full name? I still think you could use [name_m]Teddy[/name_m] as a fun nickname. [name_m]Theo[/name_m] would get you the two syllables/own letter requirements.
