[Opinions] Re: Girl's Twin Set
Audrey Elenor - love Audrey. Elenor doesn't appeal to me, since it seems dated (and I think the spelling Eleanor is prettier). The combo is nice, though I'd prefer Audrey Elisabeth/Elizabeth or Audrey Ella.
Marilyn Jaqulene - Marilyn seems dated to me, too (I think Leslie is nicer). I'm assuming that Jaqulene is pronounced "jack leen", rather than "jack lynn". I, personally, prefer the second pronunciation, but spelled Jaclyn (a favorite of mine, though Jacqueline and Jacquelyn are also nice).
If I could mix-match (and variate) the combos you've given, I'd go with Audrey Eleanor & Jaclyn Leslie.
