Gwin
A Cornish and Welsh surname that likely comes from a word for “white” or “fair.”
The #7,006 most common surname in the United States (2010 Census) — about 1 in every 64,578 Americans shares it.
Etymology
The surname Gwin is usually explained from Celtic forms meaning “white” or “fair,” especially Cornish gwyn and Welsh gwyn. Early surname books also connect it with related spellings such as Gwyn, Gwynn, Gwynne, and Gwynneth. In that tradition, the name began as a descriptive nickname rather than a place-name or occupation.
History
The name is especially well attested in Cornwall, where modern surname dictionaries group Gwin with several close Cornish spellings. Welsh and Cornish forms have long been interchangeable in older records, which helps explain the many variants. In later English usage, the spelling often simplified to Gwin or Gwinn.
