Hello ! I'll try to help. Please bear in mind I'm not American/British and English is my second language !

Ada - too short for my liking
Louisa (does this feel dated because of Louise?)- It does feel dated to me, I like Lou better
Norah (ruined by stockings?) I don't know the stockings but not fond of the name, sounds old-fashioned to me
Audrey (too soon?)- I like Aubrey much better
Lena - to me that's a diminutive of Elena, not a name in its own right. I like Lana though
Jane (boring?)- a bit, sorry
Nancy (too tragic?) - old-fashioned I think
Adeline - I like it
Dorothy - is fine, though it really makes me think of the wizard of Oz
Jemima - original but not unheard of, I like it

Leo - bit too common these days
Walter (pretentious?) - not pretentious but sounds very "late 19th, early 20th century" to me
Henry - name's okay but not super original
Ralph - I like it. Classic but not boring
Roland - same. Like it.
Robin - not too keen on it - reminds me of Robin Hood.
Peter (dull?) - Fine though not very original

Ada - Like
Louisa - Not keen, bit dated and don’t like Lou as a shortening
Norah -Love
Audrey - Like
Lena - Not too my taste
Jane - Like
Nancy - Like
Adeline - Bit too flowery for my taste
Dorothy - Like and love Dotty as an abbreviation
Jemima - Again, not to my taste

Leo - Like
Walter - Love
Henry - Not keen
Ralph - Too associated with Forever by Judy Blume for me but that may just be my age...
Roland - Not keen
Robin - Like
Peter - Quite Like

Have you considered: Ivy, Jean, Valerie for girls? Vincent, Ivan, Lester for boys?

or not oe. And it's a no.

Ada - don't like it. First Aider.
Louisa (does this feel dated because of Louise?) - no. it's lovely.
Norah (ruined by stockings?) - Flamin' Norah. Norah Batty.
Audrey (too soon?) - Audrey Roberts. Nuff sed.
Lena - Leena oe Layna?
Jane (boring?) - lovely.
Nancy (too tragic?) - it's ok
Adeline - awful sorry. Add-a-line.
Dorothy - love Dot as a nn
Jemima - lovely

Leo - nice but way too popular
Walter (pretentious?) - don't like it
Henry - popular but sounds a bit wet
Ralph - no. Ralf or Rafe... Just no
Roland - ok
Robin - ok
Peter (dull?) - love it.

Ada- bland
Louisa-really like.
Norah-dreary. It does have stocking connotations to me.
Audrey- great. Audrey Hepburn.
Lena-OK but bland.
Jane-really like. Simple and classic.
Nancy-only if short for Anne or Anna.
Adeline-Victorian style of name that’s already dated.
Dorothy- OK but I’m not wildly keen.
Jemima- pretty sound but it has Deep South connotations to me. Aunt Jemima.

Leo- nice but popular.
Walter- I quite like this. But you might get Wally.
Henry-nice, classic.
Ralph-like.
Roland-surprisingly I like this. Childe Roland. But might be hard to pull off. Still got an old image.
Robin-not keen. Too babyish but OK as short for Robert or Rupert.
Peter-like this. Due a comeback.
