I like [name_f]Claire[/name_f] as a middle name…it’s one syllable like [name_f]Rose[/name_f].
Like a previous poster, I love [name_f]Alexandria[/name_f]…[name_f]Alexandria[/name_f] [name_f]Claire[/name_f]? You’d still have all of the nickname options as you would w/[name_f]Alexandra[/name_f], but [name_f]Alexandria[/name_f] is more unusual & distinctive. There’s also [name_f]Alexandrine[/name_f], or [name_f]Alexandrea[/name_f], or [name_f]Alexa[/name_f].
W/[name_f]Audrey[/name_f] I find [name_f]Elizabeth[/name_f] to be too long…maybe [name_f]Eliza[/name_f]? [name_f]Audrey[/name_f] [name_f]Rose[/name_f] & [name_f]Eliza[/name_f] [name_f]Claire[/name_f]?
[name_f]Olivia[/name_f] has been popular for quite a while & is also long to my ear w/[name_f]Audrey[/name_f]…maybe [name_f]Livia[/name_f] instead? [name_f]Audrey[/name_f] [name_f]Rose[/name_f] & [name_f]Livia[/name_f] [name_f]Claire[/name_f]?
Good luck!
