For big sister named Un@, do you prefer little sister @udrey or M@rgot?
[name_f]Margot[/name_f]/[name_f]Margo[/name_f] with [name_f]Una[/name_f] for sure
[name_f]Una[/name_f] and [name_f]Audrey[/name_f] sound nice together, but style wise, [name_f]Margot[/name_f] and [name_f]Una[/name_f] are closer. It really depends which name you prefer. 
I think Un@ and M@rgot work best together. A very pretty sibset.
[name_f]Margot[/name_f], for sure.
I really think either work!
I prefer [name_f]Margot[/name_f] and [name_f]Una[/name_f], but [name_f]Audrey[/name_f] and [name_f]Una[/name_f] work great too!
Most everyone has said M@rgot. Can you explain why M@rgot goes better? [name_m]Just[/name_m] wondering what it is that makes them stylistically similar. Thoughts?
[name_f]Margot[/name_f] and [name_f]Una[/name_f] fit better stylistically. They both are a bit quirky while [name_f]Audrey[/name_f] leans more to the classic side of naming styles.
To me, @udrey has a very classic vibe, sort of buttoned-up feeling. M@rgo is a bit more spunky, which is the trait I feel it shares with Un@.
I agree 
I like [name_f]Margot[/name_f]/[name_f]Margo[/name_f] with [name_f]Una[/name_f] because the “oo” sound in [name_f]Una[/name_f] is similar to the “oh” sound in [name_f]Margot[/name_f]. [name_m]Both[/name_m] have these sort of non-traditional sounds for feminine names.
I think [name_f]Margot[/name_f]/[name_f]Margo[/name_f] and [name_f]Una[/name_f] go together better than [name_f]Audrey[/name_f] and [name_f]Una[/name_f]. [name_f]Audrey[/name_f] sounds more classical than the quirky [name_f]Margot[/name_f] which works well with the unique [name_f]Una[/name_f]
I think [name_f]Margot[/name_f].
