Definition: The word "Richard" is a masculine noun with the suffix "-son". It can be used to refer to any male member of a family, such as Richard III or Richard III's son. A male family member who is named after a person in history is called a Richardian. For example, King Richard I was one of these Richardians, and he was king from 1199 until his death in 1216. Richardson's name is derived from the Old French suffix "-son" (or "-ron") which means "son," "sonny," "sonnier," and "sonnier." So it could be a name for a male son, but also possible to refer to a person who has been called Richard.
