I can't get over Winterose. I think it's very pretty! I've always had a soft spot for Eilonwy, Everlid, and Illyria. These are my top 5 of the list you posted with middles:
I think my favorite of all of them is Eilonwy Arcadia or Winterose Elaine.
How is Eilonwy pronounced?
Thank you all so much!
lineska: We're going to try and get Villanelle in there, I love the Hespera Tempest Villanelle combo!
mara_lyn86: I don't know if Tinuviel had any other roots, I do love Tolkien though, so no problem for me if it hasn't...
asophie1: I love Altalune Windemere Snow! So beautiful!
sheflieswithherownwings: Great to get input from a teacher. Seawillow is an actual name, I think it's adorable! i had to get used to saying it first though. I love so many of the combos you suggested, Belphoebe Tinkersnow Ren and Ceridwen Finvola Meadowsweet are fantastic.
klcalder2: I love Winterose too, it's stunning. I find myself writing it on notepads...
flick: Eilonwy is pronounced aï:-lonwi (first i long, second short).
