Another interesting one I would see a lot is <mother's father's name> <father's father's name> <last name>.

For example, My dad was Charles Marvin Gore. His mother's father was Charles Maltbie. His father's father was Marvin Gore.

I don't think I ever saw the two modes combined though, so no example of a Charles Marvin Maltbie Gore. Although that is just in my family. It might have happened in others.
