Merredith is a rare and distinctive given name of Welsh origin, derived from the ancient Welsh personal name Meredydd, which means "great leader" or "eminent chief". It has been predominantly used as a male name but can also be found among females in some cases. The name gained minor popularity during the Middle Ages due to Saint Meriadoc, a Breton monk and bishop who was venerated as a saint after his death. Merredith is not currently widespread and remains an uncommon choice for parents seeking a unique name for their child. It offers a strong and historic sound with a touch of rarity that sets it apart from more common names.
The name Merredith had its peak years of popularity between 1975 and 1980, with a total of 35 births occurring during this period.
