I would either pick [name]Charlotte[/name] - it definitely goes and I don’t think the origin of her name is going to make her feel left out - [name]Anthony[/name] is not an Italian name, it’s a name used by many Italian-Americans and other people. [name]Antonio[/name] or Antonino is Italian, while [name]Anthony[/name] is the English form of it. So [name]Charlotte[/name] would be fine. People will call her [name]Carly[/name] if you call her [name]Carly[/name] - she will know herself as [name]Carly[/name] and introduce herself to people. This is not difficult. She may have her own ideas as she grows older, which is fine - many people grow out of their nicknames.
[name]Luciana[/name] would also be great. It is my opinion that you can say this name two ways, and maybe if you didn’t strictly insist on the Italian pronunciation, this would be a great match also. If you are pronouncing [name]Lu[/name]-chee-ah-na, how are you saying [name]Isabella[/name]? Are you flourishing both names with rich Italian pronunciations or just [name]Luciana[/name]?
As far as matching - you are going in the right direction when you say you don’t want your DD to feel like an oddball. [name]Addison[/name] is so masculine/unisex and trendy next to [name]Isabella[/name] and [name]Rocco[/name]. I really think it is weird in this context. It might go with [name]Anthony[/name] if he were the only other child at this point. [name]Jocelyn[/name] might be pretty with [name]Isabella[/name] - I’m not sure yet. They seem to sound similar but completely unrelated, so it’s off. [name]Isabella[/name] is a popular name, while [name]Jocelyn[/name] is just not on most people’s radar. While I love [name]Jocelyn[/name], I don’t think it makes a great set.
I am wondering because you have suggested so many names which are not Italian, what causes you to impede the use of [name]Luciana[/name] with a strict Italian pronunciation? You can say [name]Lu[/name]-chee-ah-na and [name]Lu[/name]-see-ah-na are both correct - the 2nd is not a massacre, that’s just how we say it in the US. You can insist on the 1st but be relaxed if people speak in their mother tongue - it is not butchering! Unless you are having the same trouble with people pronouncing [name]Isabella[/name] like “iz-a-bell-a” when you are saying it Ee-sah-b”-lah, then you probably should accept that [name]Luciana[/name] is Italian in origin, but people in the US have adapted their sense of language to it - and that is correct also. Or not worry so much about [name]Charlotte[/name] not fitting in while [name]Anthony[/name] is an English name.
[name]Luciana[/name] and [name]Charlotte[/name] are your best bets right now. You had a poll, and I also like [name]Natalia[/name]. I think the 4th best is [name]Jocelyn[/name]. She might feel sort of odd - it’s likely she won’t notice her name is not like the others. It’s as pretty as [name]Isabella[/name]'s name, so I don’t feel like there will be a sort of “rivalry” when they are teenagers, which one has the pretty name and which one has the plain name, or the boyish name and the very girlish name - matching names up in style and effect may come into play when they are old enough to compare which name is better and why they fit their name or not, who got the raw deal or whatever. By keeping them sort of even, at least you won’t have that. They have feminine appeal in the long form with spunky nicknames to suit a more streamlined personality if they prefer.
I don’t think [name]Jocelyn[/name] will make her feel like an oddball, but it just doesn’t look right to me. [name]Jacinta[/name]? Or Italian, [name]Giacinta[/name]. It sounds almost like [name]Jocelyn[/name], but very harsh next to [name]Isabella[/name]. Keep in mind, [name]Isabella[/name] is used well in the US by people other than Italians, so it goes well with other names like [name]Charlotte[/name], which is more popular, and [name]Luciana[/name] which is Italian but recognizable. It doesn’t sound right with [name]Giacinta[/name] - a very harsh sound with a very mellow sound, too disparate. [name]Jocelyn[/name] would probably be pretty enough and in the scheme of things, would be a fine choice. It just looks a little more eclectic than your other choices, but it sounds ok.
