* = I would use
Alba Wren - Alba reminds me of Jessica Alba. Wren is pretty, though.
Lumi Thistle - This just seems odd to me. I can't say I like either names.
Iris Winter - Pretty! Not sure about two nature-y names together. Prefer Winter Iris.
Tamsin Mara - Love Tamsin! It's cute with Mara.
Juna Maeve - Juna is very pretty, not too keen on Maeve.
Luca Valo - Not too sure about either names, especially not together.
Magnus Loki - No. Too Superhero-y for my tastes.
Isidor August* - Love August, not Isidor.
Cormac Rune - Love Rune, not Cormac.
Ronan Somerled - Love Ronan, not Somerled.
