Sister for Tristan

[BabyGirl23]

We have a list of names we both like but none of them feel like "the one".
Surname begins with a K and has a famous family strongly associated - we wouldn't choose Jacqueline if you get my drift!
We're pretty set on the middle name Rae.
What names would we love if we like:

Alice
Sophie
Elizabeth
Bethany
Penelope
Evelyn
Isabelle
Rosalind
Annabelle
Catherine

Names I love but which DH has vetoed for bring too unusual:

Ariadne
Meredith
Rhiannon

Have name changed for this one.

Carolyn/Caroline
Katharine
Sarah
Florence
Rose
Rosemary

Isolde?

Alice - like
Sophie - like
Elizabeth - like but pick a diminutive
Bethany - dislike it
Penelope - ok
Evelyn - dislike
Isabelle - too frilly
Rosalind - love it
Annabelle - too frilly. Like Ann, Annie and Anna
Catherine - like

Names I love but which DH has vetoed for bring too unusual:

Ariadne - not sure
Meredith - horrible as a girl's name
Rhiannon - dislike the way people say it as Ree Annun.

Maybe not Bethany or Penelope because they sort of 'rhyme' with your presumed surname. Of your list, I think Sophie works well. Or maybe Sophia?

Tristan to me is a Cornish name. Maybe Elys or Elowen?

Isolde

Alternatives-
Rebecca
Harriet
Josephine
Lucinda
Cassandra
Henrietta
Alexandra
Victoria

Out of your names my favourite is Penelope because I love the nn Penny!

Aster
Maeve
Beatrix
Elsa
Aoife
Posey
Ophelia
Arabella
Scarlett
Marilyn

Lois
Marianne
Beatrice (Bea)
Jocelyn
Jane
Stella
Cecile
Christabel
Serena
Miranda
Claudia
Oona
Caroline
Laurel
Robin
Sorrel
Frances
Carys
Zoe
Juliet
Rosanna
Rachel
Caitlin
Margot (Marguerite for full if you want)
Nancy
Anna / Annalise
Cleo

Alice - nice but dull
Sophie - goes nicely
Elizabeth - always a winner
Bethany - too rhyme-y with Kennedy
Penelope - same
Evelyn - great but done to death. I think you need something a bit unusual to go with Tristan (great name BTW)
Isabelle - same
Rosalind - Nice
Annabelle - find
Catherine - nice - Kate Kennedy is great

Names I love but which DH has vetoed for bring too unusual:

Ariadne - too much with Kennedy
Meredith - it’s not so unusual now, but Merry Kennedy is a bit odd
Rhiannon - bit of a mouthful with surname

Since Tristan is modern and simple. I say Alice or Sophie.

One of my friends has Tristan & Rhiannon - I think those names go well together.

Isabel

Ophelia
Eliza
Olivia
Anita
Louise
Elena
Esmae
Leona
Rebecca
Fay
Kate
Heidi
Charlotte
Ingrid
Zara
Sian
Melissa
Matilda.
I like all your names. Elizabeth and Sophie are my favourites.

Feliciity /Felicia
Zara
Willa
Lucille

I love Alice, so wouldn’t look any further.
Also love Rhiannon ( I have one) and Meredith.

Suggestions:

Saskia Rae
Juliet Rae
Lucille Rae
Frances Rae
Amelia Rae
Genevieve Rae
Zara Rae
Charlotte Rae
Tabitha Rae
Felicity Rae
Nina Rae
Karla Rae
Melanie Rae

Rosalind is perfect with Tristan

Olivia

A variation of Isolde is Iseult which is lovely and goes well with your surname.

I think Alice, Catherine, and Annabelle go best with your surname.

Suggestions:
Flora
Cecily
Clara
Miranda
Leonora
Cecelia
Theodora
Claudia
Lara
Finola
Juno
Ivy
Xanthe
Vivien

I'd avoid Caroline and Rosemary.

Camilla
eloise
harriet
phoebe
helena
rosanna
juliet
louisa
emmeline
esther
cassandra
grace
eleanor
lydia
serena
adeline
francesca
lucy
abigail

I forgot Helena.

Not Penelope because Penny Kennedy doesn't sound great

Loads of great suggestions to ponder. Thank you all

Tristan and ..
