Both are cool! I prefer [name_m]Ivo[/name_m] [name_m]Mercury[/name_m]. From the other options my favourite is [name_m]Ivo[/name_m] [name_m]Cyrus[/name_m]
I prefer [name_m]Ivo[/name_m] [name_m]Mercury[/name_m], as the flow feels nicer and I generally like [name_m]Ivo[/name_m] as a first name way more then [name_m]Mercury[/name_m]. I also like [name_m]Ivo[/name_m] [name_m]Cyrus[/name_m] more than [name_m]Cyrus[/name_m] [name_m]Ivo[/name_m] despite liking the name [name_m]Cyrus[/name_m] as a first name more. [name_m]Ivo[/name_m] [name_m]Banks[/name_m] is cool as well.
I’m especially smitten with your [name_m]Cyrus[/name_m] [name_m]Ivo[/name_m], but I also like [name_m]Ivo[/name_m] [name_m]Mercury[/name_m] - he’s really fun with [name_m]Fox[/name_m] & [name_m]Cassius[/name_m]! [name_m]Ivo[/name_m] [name_m]Mercury[/name_m] probably works a little better, too, because [name_m]Cyrus[/name_m] & [name_m]Cassius[/name_m] both look pretty similar. [name_m]Ivo[/name_m] [name_m]Bear[/name_m] I want to love but he feels off somehow? Maybe too abrupt? [name_m]Bartholomew[/name_m] [name_m]Ivo[/name_m] or [name_m]Barnaby[/name_m] [name_m]Ivo[/name_m] would be really sweet, though!
[name_m]Ivo[/name_m] [name_m]Mercury[/name_m] and [name_m]Fox[/name_m] [name_m]Evander[/name_m] are so handsome and well balanced together. I love the flow of [name_m]Ivo[/name_m] [name_m]Mercury[/name_m] the best of all the combos, and I think it’s a fun combination of familiar sounds and unusual names.
[name_m]Cyrus[/name_m] [name_m]Ivo[/name_m] is also really well balanced, but I worry that [name_m]Cyrus[/name_m] and [name_m]Cassius[/name_m] are maybe too close in sound? For a long lost I’d say keep them both, but for actual brothers I’d probably say it’s either [name_m]Cyrus[/name_m] or [name_m]Cassius[/name_m], not both. [name_m]Ivo[/name_m] dodges that problem altogether and is a very handsome, charming choice.
