Alice - I loooove Alice and it works so well with Graham. This is my top pick on your list for the sibset!
Audrey - My favorite name and if I don’t get to use this I will be devastated! I love Audrey and it also works. It’s a little frillier than Alice though and Graham isn’t frilly at all so that’s why my vote is for Graham & Alice.
Elinor - I dislike this spelling. My name is Erinn and having an uncommon spelling name has caused me more trauma than you know. Since Eleanor is more common, I would really suggest not using this. There’s a difference between an unusual name and a usual name spelled “wrong” that only an Erinn can say!
Judith - This feels very old lady to me. I much prefer June, Juniper, Juliana, Jules.
Vivian - Another one that usually feels old ladyish but it works well with Graham and has a plethora of beautiful nicknames.
Ingrid - I dislike this one; simply, it’s not my style and clunky. It does not look well next to handsome Graham.
Gwyneth - I generally dislike sibsets that have two of the same initials.
Meili - This is a new name you introduced me to! I like Meili a lot, but it is a very different style from Graham and the other names on your list, so I am surprised to see it here. It is beautiful, though.
Lydia - My best friend is named Lydia and she wears it well. This is a classic, gorgeous name and it would probably be on my list if it weren’t for my friend.
Greta - Another of the same initials thing.
