Rodd is a distinctive Scottish name derived from MacRath, meaning "son of Rath," itself a pet form of Raghnall, used by early Scottish kings. It gained prominence through 16th-century Highland chieftain Roderick MacRath and has since been passed down, with varied spellings like Rodd, Roid, Ruid, or Rudh. Today, it remains a powerful name with a rich history worldwide.
