I love them both, and I think [name]Eliza[/name] can completely stand alone. I can tell you this, I know an 18-year-old [name]Eliza[/name], and she never knew that her name was derived from [name]Elizabeth[/name], and she loves her name. [name]Eliza[/name] isn’t nicknamey at all to me, it’s not like naming your daughter [name]Betty[/name] or [name]Lizzie[/name]. It’s a really gorgeous name all on it’s own, and I’m trying to imagine that my name is [name]Eliza[/name], and I don’t think I’d wish to be [name]Elizabeth[/name]. TONS of names don’t have options. My name has no options, granted I don’t like my name, but that’s not why! Also, I think it definitely works for an adult in professional situations. I can picture [name]Eliza[/name] at all different ages, an artist or a lawyer, and anything in between. Very versatile if you ask me.
As for [name]Elizabeth[/name], that’s a beautiful name too! It’s one I always wished I was. It does have the benefit of options… but what if she chooses an option you don’t like! [name]Elizabeth[/name] is pretty much the ultimate classic, it’s a really wonderful name. I don’t know, very hard decision! I intend to use one of them someday, at least in the middle, for my husband’s beloved grandmother… I haven’t yet decided which to use! It’s too hard to pick!
