Geoffrey de Geneville, 1st Baron Geneville (1225/33–21 October 1314) also known as Geoffrey de Joinville, was an Anglo-French noble, supporter of Henry III, who appointed him Baron of Trim, County Meath, and, subsequently, a staunch supporter of Edward I.

Family and marriage

Geoffrey was Seigneur of Vaucouleurs in Champagne, second son of Simon de Joinville and Beatrix d'Auxonne and younger brother of Jean de Joinville.[1][2] Geoffrey's half-sister was wife to one of Eleanor of Provence's uncles, Peter of Savoy, earl of Richmond.[3] Geoffrey was thus one of the "Savoyards" who arrived in England in the retinue of Eleanor at the time of her marriage to King Henry III in 1236.

Some time between 1249 and 8 August 1252, Henry III arranged Geoffrey's marriage to Maud (or 'Mathilda') de Lacy, widow of another Savoyard, Pierre de Genève, himself also a relative of Queen Eleanor, who had died in 1249. Maud had been co-heiress to vast estates and lordships in Ireland, Herefordshire, and the Welsh Marches, and the marriage is considered typical of Henry's 'policy' of appointing such 'aliens' to retain control of the outlying regions of the kingdom.[1] Geoffrey thus came to control vast estates in Ireland centred at Trim, the Welsh borders at Ludlow, Ewyas Lacy and others in England. Maud and Geoffrey had at least four sons, Geoffrey, Simon, William and Peter ('Piers').[3]

Political and military career

Geoffrey was both a military figure and political negotiator. He successfully pacified the Irish pro-Montfort and Royalist barons at this time that assisted the future Edward I's success at Evesham. In 1267 he assisted Henry III with negotiations with Llywelyn ap Gruffudd, the year of the Treaty of Montgomery.[3] With another of his brothers, William, he accompanied Edward on the Eighth Crusade in 1270, fought in Welsh Wars, and went on diplomatic missions to Paris. He served as justiciar of Ireland from 1273 to 1276 but had little success against the Leinster Irish, being heavily defeated in 1274 and 1276. In 1280 he acted as Edward's envoy in Paris and to the papal curia, a mission repeated ten years later in 1290.

In 1282 he was assistant to the Marshal of England in the Welsh War of that year.

In 1283 He granted his English lands to his son Peter and focussed his attention on Ireland.[3] He and his wife defended their liberty rights in Trim against the Dublin government, and defined military duties for his tenants.[2]

In 1297 he supported Edward in the crisis caused by royal demands for men and money for the war in France. Edward appointed Geoffrey as Marshal of England in place of the main dissenter Roger Bigod, Earl of Norfolk until the crisis was over. Geneville subsequently received a number of summonses to parliaments between February 1299 and November 1306.[3]

Later life

Geoffrey's wife and their eldest son pre-deceased him, Maud dying on 11 April 1304.[3] In 1308, aged about eighty, he conveyed most, but not all, of his Irish lordships to Roger Mortimer, husband of his eldest granddaughter and heir, Joan. He retired to the Dominican Black Friary at Trim, that he had established 1263.[4] He died 21 October 1314 and was buried there.[2] Upon his death Joan succeeded him as "suo jure" Baroness Geneville.
