Síodháin

Síodháin is a Gaelic-language personal name used in Ireland and among the Irish diaspora, functioning as both a surname and a given name. In Irish-language sources, it appears in historical and contemporary contexts, and modern writers sometimes encounter it in genealogical records. The name is attested in regions where Gaelic culture has left a mark, though it remains relatively uncommon today.

Etymology and origins of Síodháin are not firmly documented in accessible sources. It follows patterns common to Gaelic names, and may be derived from older elements incorporated into personal names. Because of limited attestation, precise roots and meaning remain uncertain.

Variants and usage: Spelling has varied in documents due to orthographic changes and anglicization. In modern Ireland, Síodháin is more likely to appear as a surname than as a given name, but as with many Gaelic names it can be found in both contexts among families of Irish descent.

Notable people: There are no widely cited individuals with Síodháin in major reference works, which suggests the name is niche and primarily of genealogical interest. See also: Irish language names, Gaelic surnames, List of Irish surnames.
