HELP!! cant find boys name

We are having a little boy in 11 weeks and we cant find a name we both like! We like different, unusual names but not too wierd, we dont want him having the same name as everyone in his class at school. I liked Oscar but dad doesnt so its a no, the only one we agreed on was Roman but im not so sure anymore, any suggestions woudl be welcome as i can see him being born with no name!!

I also like the idea of the name beginning with C as we have 2 other children and there names begin with C, so does dads!

Thanks x
