Seamus (English)

Where does "Seamus" come from?

The English name 'Seamus' is an Anglicization of the Irish name 'Séamas'[1]. This Irish form was itself borrowed from English 'James'[3]. The name 'James' traces back through Middle English and Old French to the Vulgar Latin form 'Iacomus', which is an altered pronunciation of Latin 'Iacobus'[2]. This Latin form derives from Ancient Greek 'Ἰάκωβος', ultimately coming from the Hebrew name 'יַעֲקֹב'[2], meaning 'heel-grabber'[6].
