What ethnicity is the name sheen from?

The surname Sheen has multiple ethnic origins, but it is most commonly associated with Irish heritage. In its Irish form, Sheen is an anglicized version of the Gaelic surname O'Shea or O'Seaghdha, which means descendant of Seaghdha. Seaghdha is an old Gaelic personal name meaning hawk-like, majestic, stately, or learned. The O'Shea clan originated in County Kerry in southwestern Ireland and is one of the prominent Irish families. When Irish families emigrated and anglicized their names, O'Shea often became Shea and sometimes Sheen. There is also an English origin for the surname Sheen. In England, Sheen can be a topographic or locational surname derived from Old English words meaning beautiful, bright, fair, or shining, or from place names like Sheen in Staffordshire or East Sheen in southwest London. In this English context, it means someone who lived near a beautiful place or a shed or shelter. So the name Sheen can be Irish or English, but the most well-known association in America due to actors Martin Sheen and Charlie Sheen, whose original family name is Estévez from Spanish and Irish ancestry, is Irish. The name is predominantly found in Irish diaspora communities.
