A Scottish and Irish surname, from Scottish Gaelic.
"The Boyd family has a long history in Scotland as a prominent clan bearing that traditional surname."
The name Boyd likely comes from Scottish Gaelic, derived either from buidhe, meaning "blond" or "yellow," or as a habitational surname referring to the Isle of Bute in Scotland. It entered English usage primarily through its adoption as an aristocratic family name rather than retaining any direct descriptive meaning related to hair color.
