Isla - I have always liked it, but depends if you mind how common it has become
Alma - Love this but didn't immediately because it was still in "old lady" camp when I met the child I know. She's a sweetheart, and people definitely do change my opinion on their names!
Rosa - Wouldn't choose it myself but wouldn't make a face about it
Ruby - Don't like it... again because of ones I've known though. They all have parents I can't help but judge (secretly of course)
Nell - I really like it. I prefer long versions of names as a rule even if never used, but that's just personal preference!
Rosalind - Don't like it, haven't met anyone to take it out of old lady camp yet though
Romilly - I don't know it as a name and would have assumed boy! But that's my ignorance and I think they'd become Romi which I think is quite cool.
Ocean - No.
Nelly - the elephant?
Elowen - pretty but agree it could be frustrating re spelling/pronunciation
Teigan - I think it's ugly
Karenza - I don't like either if these, not sure if it is the "za" endings that put me off
Demelza
Lillian - Horrible old lady I knew as a kid, I cannot give it a fair trial
Guinevere - I don't immediately love it but could definitely grow on me
