[name]Hi[/name], [name]Annetta[/name]!
I [name]LOVE[/name] [name]Hugo[/name] and [name]Julius[/name], as well as all of the names you’re considering!
[name]Lucien[/name] and [name]Louie[/name] share the OO sound in the beginning, like [name]Hugo[/name] and [name]Julius[/name]. Since they’re kind of similar, what about [name]Lucien[/name] with the nickname [name]Louie[/name].
If you’re in the US, [name]Theodore[/name] fits best popularity-wise…
[name]Henry[/name] fits well, but is a bit too popular and repeats first initials with [name]Hugo[/name], if it bothers you…
Depending on where you are, [name]Oscar[/name] may or may not be too popular For example, [name]Oscar[/name] is only #130 nationally, but in the Top 100 in some states. Stylistically, I think they fit, but I agree, for some reason, they’re a bit off. I guess that [name]Oscar[/name] feels a little less romantic sounding to me?
I love [name]Olivier[/name], but I think that it could be pronouced incorrectly (o-liv-ee-er rather than o-liv-ee-AY?) and mistaken for the more popular [name]Oliver[/name].
Now that I think about it, [name]Lucien[/name] and [name]Augustin[/name] are a bit unusual with [name]Hugo[/name] and [name]Julius[/name], but they fit very well nonetheless!
Hmm… My favorites from your list would be [name]Theodore[/name], [name]Augustin[/name], and [name]Lucien[/name] (nn [name]Louie[/name]?)!
From [name]Michaela[/name]'s suggestions, I particularly like [name]Edmond[/name] (or [name]Edmund[/name]?) with [name]Hugo[/name] and [name]Julius[/name]!

Which one sounds best with your surname?
Good luck!
