Seadhna is a name of Irish origin, traditionally given to boys. Its official translation is a bit of a mystery, but it’s often seen as a variant of Séadna, related to the name Sidney which means “wide island” in Old English. Your interest in Seadhna may have also been inspired by writer Peadar Ó Laoghaire, whose Faustian tale, Séadna, is considered a cornerstone of modern Irish literature.
