Short, polysyllabic names

[meditrina]

Can you help my cousin?

Her surname is a short (4 letter) thuddy monosyllable. She wants to balance this with a first name which is polysyllabic (3, ideally 4 or more syllables) but with as few letters as possible (so they don't look too ridiculous next to each other). She doesn't want to use the initials F or S.

Any ideas I could offer her?

Leonie/Leona

Amelia

Btw, she doesn't know if it's a boy or a girl, so suggestions for both sexes welcome.

Iona
Lydia
Tabitha
Evelyn
Talia

Gabriel
William
Cassius

Difficult to find one with few letters!
What sort of names does she like? Modern, traditional, fashionable?
Boy/ girl or both?

Ophelia
Aurora
Beatrice/Beatrix
Naomi
Marianne
Arabel/ Annabel
Isobel
Rebecca
Tabitha
Vivienne

Nathaniel
Catherine (Katarina)
Alexander (Alexandra)
Penelope (well, I think it's cute)
Sylvia (old un, but good un) - oh, just saw the S ban :o
Marianne/a
Polixenes (only joking!)
Imogen
Hermione

this is fun - I'm sure more people will join in soon

Hmm, tricky one.

Ariana
Jessica
Jennifer
Tahlia
Cecily
Cecilia
Peony
Helena

Lionel
Theodore (Teodor?)
Maximus
Oliver

I'm not sure - are these too long?

Tobias
Lucien
Gregory

Natalie

I'm seeing her at the weekend, so will be able to try them out on her then. I'd guess she'll be traditional, but in an educated mildly bohemian way IYSWIM.

Of the suggestions so far I really like Leonie (she's a Georgette Heyer fan), Amelia, Tabitha, Thalia, Annabel (there's an Isabel elsewhere close in the family), Cecily and perhaps Peony (Penelope is nice, but perhaps top long). For boys, Cassius, Maximus and Tobias look good so far.

(I thought of Vercingetorix, but it's far too long!)

Oh I love threads like this!!!

Polly (and it's polysyllabic :o)

Girl: Rowena, Isabel, Emily/Amelia, Elena/Helena, Marina.
Boy: Gabriel, Jonathan, Timothy, Gideon, Adrian.
Might help to choose a name that's compatible with the family's ethnic or religious background too, which we don't know here, but hopefully the pool of suggestions will help.

Sorry, just saw your post about Isabel already being taken - ok, another vote for Naomi then.

Emily/Amelie/Emilia/Amelia
Merrily (I'm sure I've seen this used as a name somewhere - i think it's really pretty!)
Rhianna
Melissa

Gregory
Harrison
Christopher
