What does Sean mean?
The Irish form of John (Seán), borrowed from Norman-French Jehan, ultimately from Hebrew 'Yochanan' meaning 'God is gracious.' Anglicised variants include Shawn and Shaun.
What does Connor mean?
From the Old Irish Conchobar, usually read as 'con' ('hound', sometimes extended to 'wolf') plus 'cobar' ('desiring'), hence 'lover of hounds' or 'wolf-lover'. The wolf sense is secondary to 'hound' and the early elements are debated, so the wolf connection is DISPUTED and flagged.
