What Lorcan means
Lorcan means little fierce one, or little cruel one. The root lorc is a strong word — fierce, cruel, savage — and the diminutive softens it into something closer to young fierce one than to anything mild.
Where Lorcan comes from
Lorcan anglicizes the Irish Lorcán, from lorc, fierce or cruel, with the diminutive -án. Lorcán mac Lachtnai was a tenth-century king of Thomond and the great-grandfather of Brian Boru, which puts the name at the root of the O'Brien line. Its saint is Lorcán Ua Tuathail, known in English as Laurence O'Toole, who became archbishop of Dublin in 1162 and was in office when Strongbow's Normans took the city in 1170; he negotiated between the Irish kings and the invaders, died at Eu in Normandy in 1180 and was canonized in 1225. He is the patron saint of Dublin. The English form Laurence attached to him by sound rather than sense — Laurence is Latin, from Laurentum — and the pairing is one of many where an Irish name acquired an unrelated English partner during the centuries when Irish names were not registrable.
