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.
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 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.
He retired to the Dominican Black Friary at Trim, that he had established 1263. He died 21 October 1314 and was buried there. Upon his death Joan succeeded him as "suo jure" Baroness Geneville.
