Not Lucas, doesn't work with our surname and ends up sounding like Luca anyway.
I like it but kind of feel you'd need to be Italian to use it (irrational I know), and main concern is that it seems pretty popular? Don't think I've met any at baby groups but I know a friend of a friend has one.
Arrrrrgh, I don't know if it's 'us'. Naming boys is hard :(
