Walsh surname meaning

Walsh is an Irish surname derived from a Middle English form of Welsh. It began as an ethnic nickname for a Welsh person, Welsh speaker, or newcomer associated with Wales, and it became established in Ireland in several communities. The Irish form Breathnach carries the same broad ethnic idea, while Walshe, Welsh, and Welch show related English spellings. A Walsh family therefore cannot be assigned one guaranteed ancestor or one Welsh locality from the surname alone. Nickname is the high-confidence catalog type because the name records an identity or origin byname. Later American Walsh lines may preserve several separate Irish and Welsh-connected histories.
