Gilbert de Lyvet

Gilbert de Lyvet (died ca. 1244) was an early Anglo-Norman nobleman and merchant who became one of the earliest Mayors of Dublin. He donated extensive properties to the Cathedral of the Holy Trinity in Dublin, acted as witness for early gifts to the cathedral, and was a partisan for the Bigods, the de Clares, the de Lacys and other Norman magnates.

The birthplace of Gilbert de Lyvet is unknown, although he was likely born in Sussex, England, where the Levett family had their seat from about the time of the Norman Conquest. The family later became Lords of the Manor of Firle, Sussex, and received extensive grants of land across the south of England. They were sublords of the de Ferrers family, originating from the village of Livet in Normandy within the original de Ferrers barony.

Gilbert de Lyvet was a citizen of Dublin from 1229-1244. He served as Mayor of Dublin for four one-year terms, 1233–1234, 1235–1236, and was re-elected for a third term from 1236-1237. de Lyvet was frequently engaged in business in the city, and was a partisan of the most powerful Norman lords of Ireland. He was a witness to a 1210 gift by Isabel de Clare, 4th Countess of Pembroke to The Cathedral of the Holy Trinity, in honour of her father Richard de Clare, 2nd Earl of Pembroke, whose 'Strongbow' tomb is within the Cathedral. de Lyvet was also a merchant with wide trading interests, and old Irish records note that he often traded with France using his own ships. He is frequently in Latin charters relating to church business in Dublin.
