Are Celtic people black?

I was told that in Africa there are a lot of Celtic genes. Then there are a lot of Black people with names like Eddie Murphy, Isaac Hayes, Shaquille �Neal, Dizzy Gillespie, Mariah Carey,Clarence Thomas, Carmen McRae, Myles Davis, James Earl Jones, Carl Lewis, Kobe Bryant. They all have Celtic surnames. I have a Celtic surname. Does that mean I am Black?
