Opinions please

Looking for some opinons please! This is what we've narrowed our list down to... Which first/middle name combos would you make out of these names? As well as some pairings - B/B, B/G and G/G as it's too early to tell what we're having yet. It's still early days but we're trying to remain positive and just organised really as I feel so unprepared... Two sacs, yolks and fetal poles were found at our private scan but only one heartbeat. I'm not as far along as I thought so we're going for another scan on Tues to confirm. Opinions on whether you'd keep or nix our maybes (based on why they're maybes) would be appreciated too!

Boys...
Firsts: Elias, Elijah & Zachary

Maybes: Arthur & Sebastian - Too Disney with a sister Aurora? I'm not sure on initial sharing with Aurora/Arthur either. Dominic - Not sure on Dom which seems to be the natural NN (we'd use Nic or Nico)

Middles: Rafferty, Rowan & Tadhg (Tige... Like tiger with no R)

Girls...
Firsts: Cecily, Elodie, Felicity, Imogen, Margot, Penelope & Phoebe

Maybes: Beatrix - We don't like the shortened form, Trixie - we'd use Bea but is it inevitable? Florence, Primrose & Winter - Not sure if we want to use another nature name as both daughters have them. Primrose & Winter are probably too different in style to our LO's names too.

Middles: Aine (Awn-ya), Aisling (Ash-Ling), Brighid (Breedj), Caoimhe (Kwee-va), Cliona (Clee-Uh-Na), Eilis (Eye-Leesh), Eimear (Ee-Mer), Erin, Orla(ith), Oona/Una, Roisin (Ro-Sheen), Saoirse (Seer-Sha) & Sorcha (Surk-Ha)

We're in Ireland (DH is Irish) so we won't have any issues with pronunciation - All our LO's have Irish middle names. Sorry for the long post! Thanks, L. Xx
