Looking for honest (but kind) feedback on a name.

We are thinking of naming our daughter Lis Paul [Last Name] but we want to keep it a surprise from our family and friends. Therefore we can't get their feedback. So I'm seeking yours :-) 
What are your first reactions to this name? 
It's a very sentimental name for us, but I know it's not reasonable to think that sentimentality will protect a child from confusion and misunderstanding regarding their name. What do you think?
