Merren is in Origin.

Merren is a modern Celtic-leaning given name often treated as a spelling variant of Irish Muireann or Muirín. In Irish, muir means “sea,” with Muireann commonly glossed as “sea-fair/white,” and Muirín as “little sea,” so Merren is typically read with maritime meanings. The spelling also echoes Scottish Mirren, linked to the medieval Saint Mirin of Paisley, and overlaps with Cornish Merryn, a saintly place-name in Cornwall - connections that lend the name a pan‑Celtic feel and support both feminine and unisex use.

As a forename, Merren is seldom attested before the late 20th century, but it has gained modest contemporary appeal alongside related forms. Variants and cognates include Muireann, Muirín, Mirren, Merryn, Merrin, and Murrin; surnames Merren/Merrin also feed into usage. While spellings vary by region, the prevailing sense remains seawashed and luminous, balancing tradition with a fresh, streamlined look.
