Son of the chief of Hy Murray Taken as a hostage by King Dermot McMurrogh Leinster in 1138 when he was ten years old; Dermot later married Lawrence's sister Mor. Released in 1140 at age twelve to the Bishop of Glendalough, and raised and educated at the monastic school there. Monk at Glendalough. Abbot of Glendalough in 1153. Declined the bishopric of Glendalough in 1160, citing his unworthiness. Ordered to accept the archbishopic of Dublin in 1161, he became the first native-born Irishman to hold the see.

    Reformed much of the administration and clerical life in his diocese. Worked to restore and rebuild Christ Church cathedral. As archbishop he accepted the imposition onto Ireland of the English form of liturgy in 1172. Noted for his personal austerity, he wore a hair shirt under his ecclesiastical robes, made an annual 40 day retreat in Saint Kevin's cave, never ate meat, fasted every Friday, and never drank wine - though he would color his water to make it look like wine and not bring attention to himself at table. Acted as peacemaker and mediator at the second siege of Dublin in 1170.

    In 1171 he traveled to Canterbury, England on diocesan business. While preparing for Mass there he was attacked by a lunatic who wanted to make Lawrence another Saint Thomas Beckett. Everyone in the church thought Lawrence had been killed by the severe blow to the head. Instead he asked for water, blessed it, and washed the wound; the bleeding stopped, and the archbishop celebrated Mass.

    Negotiated the 1175 Treaty of Windsor which made upstart Irish king Rory O'Connor and vassal of king Henry II of England, but ended combat. Attended the General Lateran Council in Rome in 1179. Papal legate to Ireland. Died while travelling with King Henry II, a trip taken as a peacemaker and on behalf of Rory O'Conner. It resulted in his imprisonment and ill-treatment by the king who decided he had had his fill of meddling priests.

Born 1128 at Castledermot, County Kildare, Ireland

Died 14 November 1180 at Eu, diocese of Rouen, Normandy, France of natural causes; buried at the abbey church at Eu; so many miracles were reported at his tomb that his relics were soon translated a place of honour before the altar; his heart was removed and returned to Christ Church Cathedral, Dublin, Ireland

Canonized 1225 by Pope Honorius III
