Whats in a name?

We have been having problems figuring out baby names that Mark and I can both agree on. With the girls it was easy! I made a list and Mark would veto the names he didn't like and we narrowed it down to one boy and one girl name. With this baby, I've made about 5 lists and we can't agree on any name for boy or girl. I know some people wait til the baby is born to decide on a name, but I"m the type that likes to have a name and kind of get used to it before the baby is born. Not sure that is going to happen with this baby.
I think this is also the first time we haven't told people the name that we have chosen, because we don't have any names to tell. There were a few names that I really liked, but Mark vetoed them because he didn't like them or because he associated the name with something else. With such a big family and many friends who have had or are having babies, its hard to figure something out. We don't want to pick the same name as someone else or have a similar name as someone else. I'm starting to get a little worried that we will never come up with a name and we will walk out of the hospital with a no-name child.
I guess with 1 1/2 weeks left I better hit the books and figure something out. I'm open to suggestions, but remember I don't want anything crazy, weird or a name that is so common that there will be multiple people with that name. AHH!! Who knew it would be so complicated to pick a name?!?
