… and why! We have posted on here before but are still struggling to find his name, so we have expanded our list.
It’s between:
[name_m]Mateo[/name_m]
[name_u]Leo[/name_u]
[name_u]Elliot[/name_u]
[name_m]Hugo[/name_m]
[name_u]Luca[/name_u]
Sister’s name is [name_f]Isabel[/name_f], although it’s not so important to us that the name “goes”, we just want to love it! And it must be easily pronounceable in [name_f]English[/name_f] and Spanish. Thank you!
[name_f]My[/name_f] personal favorite is [name_m]Mateo[/name_m]. I just love the sound. It just seems to roll off the tongue and is fun to say.
[name_m]Mateo[/name_m]!
[name_u]Luca[/name_u]!
[name_u]Elliot[/name_u]! Such a sweet but versatile name!!
mateo !
It’s between [name_u]Leo[/name_u] and [name_m]Hugo[/name_m] for me - [name_m]Hugo[/name_m] wins if I absolutely have to pick one, though! I like [name_u]Leo[/name_u] for how international it is, and it’s relaxed, laid-back feel. [name_u]Leo[/name_u] is quite popular though (at least where I am) so [name_m]Hugo[/name_m] is a bit more unexpected. I also love Hugo’s meaning.
[name_f]My[/name_f] choice is [name_u]Elliot[/name_u] or [name_m]Hugo[/name_m]!
luca or elliot!
just sweet and simple but very wearable
[name_u]Elliot[/name_u] and [name_m]Hugo[/name_m] 
[name_u]Luca[/name_u] and [name_m]Mateo[/name_m] are my personal favourites from your list but I think all options are wonderful.
[name_f]My[/name_f] favorite is [name_u]Luca[/name_u]! But any of them would work
All your names are amazing but [name_m]Hugo[/name_m] feels next level !!!
I’m not sure why I love [name_m]Hugo[/name_m] with [name_f]Isabel[/name_f] it just flows so well ! It’s international , handsome and ages well. I think I like it because it is not as popular in our circles ! I only know 1 [name_m]Hugo[/name_m]
Generally and with [name_f]Isabel[/name_f] I love [name_m]Hugo[/name_m] and [name_m]Matteo[/name_m], and I also like [name_u]Luca[/name_u] and [name_u]Leo[/name_u]. All of these are lovely with [name_f]Isabel[/name_f] but my favourites are definitely [name_m]Hugo[/name_m] and [name_m]Matteo[/name_m]. I love Hugo’s strong, sophisticated vibe and Matteo’s Mediterranean - but also very international - flavour.
[name_u]Love[/name_u] [name_f]Isabel[/name_f] and [name_m]Hugo[/name_m] together! [name_m]Hugo[/name_m] is so dashing and international.
[name_m]Mateo[/name_m] - This is so handsome, and the meaning is nice as well. I think it rolls off the tongue well, I feel like you can match this with any middle and it will be great
[name_u]Leo[/name_u] - too popular for my taste, also feels unfinished or more like a nick name than an actual stand alone name.
[name_u]Elliot[/name_u] - I love this name, it’s not too popular it’s not too stuffy, it’s a solid name. *also you can use the nick name [name_u]Leo[/name_u] for this one
[name_m]Hugo[/name_m] - This has an old world charm to it for me, gives me the same brooding masculine air as a [name_m]Bruce[/name_m] or an [name_m]Otis[/name_m] but cooler
[name_u]Luca[/name_u] - This is ok but like [name_u]Leo[/name_u] I feel it looks and sounds unfinished (maybe I’m too used to [name_m]Lucas[/name_m] lol)
[name_u]Elliot[/name_u] & [name_u]Luca[/name_u] 
[name_f]My[/name_f] vote would go to either [name_m]Mateo[/name_m] or [name_u]Leo[/name_u]! Both have musical sounds in both [name_f]English[/name_f] and Spanish and seem to fit well with [name_f]Isabel[/name_f] and are.
[name_m]Mateo[/name_m] is adorable!
[name_u]Leo[/name_u] or [name_m]Hugo[/name_m]!
