Well shoot, I never thought of that! The main character in volume 2 of my series is named "James," do you think I should check with Google or is that okay?
I do not, for the reasons mentioned above. I would try to avoid any really famous names like "Harry Potter" or "Sherlock Holmes" and one of my pre-readers suggested I change one of my villains names which was "Yorik."
For KEY characters / titles/ etc that are made up I will Google to see if it comes close to anything, just to avoid name association.
