I don't think so. My name is Eloise (ell-oh-ees), and I love it. Although it's taken me 20 years to think so, becuase I hated it when I was growing up.
It's only now that I want to be unique that I appreciate having a rare name. And before anyone says it's hippy or new-fangled or made up, it's been around since medieval times.
I have to agree with Briana about the bookmarks and keyrings. I think my dad found one, and I still have it because I doublt I'll ever find another one. I normally settle for Ellie (my nickname) or Rose (my middle name)
EDIT - Liineli - I have a cousin called Joke! It's literally translated as "Little Jo", and a well-known nickname for Joanna and Josephine in some parts of Europe. I think it's a beautiful name though. My cousin doesn't live in an English-speaking country, but she's worked in a few, and she's never had any problems. Perhaps if she'd been in school in England/US, she may have had teasing, but not as an adult.
