Origin of the O'Rourke name
Woulfe: the O'Rourkes of Breifney 'were chiefs of the great clan of Ui Briuin Breifne', covering the present Leitrim and Cavan. After the 12th century their power declined: O'Reilly became lord of East Breifney (Cavan) and O'Rourke's lordship was confined to West Breifney (Leitrim), 'known as Breifney-O'Rourke'. A smaller Ui Maine branch lived in Co. Galway.[1]
