Shann is a rare, unisex given name of uncertain origin, possibly derived from Irish or Scottish roots, or from Welsh Shaun/English Shannon. Its meaning is unclear but often associated with the Irish surname O'Shannon, meaning "from Shannon," referencing Ireland's longest river. Some suggest it could be a variant of Shaun/Sean, meaning "god is gracious." Despite its rarity and mystery, Shann has gained popularity for its unique sound and spelling.
