Etymology: Robertson is a patronymic surname, meaning "son of Robert," built from the given name Robert plus the English suffix "-son." The name Robert itself goes back to Frankish "Hrōþiberhta," from Proto-Germanic roots meaning "fame" and "bright," so the surname carries a compound of "bright fame" inside it, passed down through Anglo-Norman "Robert" into English. The suffix "-son" comes from Old English "sunu," meaning "son," which was used in Middle English as "-son" to form family names. Bearers of Robertson are therefore the sons of a man named Robert, a naming pattern that was common across English and Scottish surnames.
