Following his father's death, Philip's elder brother, Ralph, inherited estates at Belvoir, Ingleby, Saxilby and Broadholme. Ralph, however, later defected to the French in 1205. Philip and at least two of his brothers entered the service of Robert de Breteuil, earl of Leicester, and he was granted the manor of Waltham. Philip was present at the signing of Magna Carta as a member of the king's party, and was mentioned within the document. He participated in First Barons War and was leader of the royalist forces in Kent and Sussex. He participated in the Battle of Lincoln in 1217, and commanded a ship during the Battle of Sandwich later that same year. Following the Pro-Angevin victory in the war he was made the tutor of the young Henry III. For his role in the king's education, d'Aubigny was granted the manors of Chewton Mendip and South Petherton in Somerset, and Bampton in Oxfordshire.
Death and burial
In 1235, d'Aubigny set out on crusade with his brother Oliver. However, Philip died in the Holy Land a year later, and was subsequently buried in front of the Church of the Holy Sepulchre at Jerusalem. His inscribed ledger stone displaying his arms was discovered in 1925, in excellent condition, and was lowered slightly below floor-level to protect it from future foot-fall wear and covered by an iron grille. The official record states:
Succession
As Philip left no legitimate children, his estate in South Petherton and a majority of his Lincolnshire lands were granted to his nephew, Ralph d'Aubigny, the brother of Philip the younger.
Family
Philip d'Aubigny was the son of Ralph d'Aubigny and Sybil Valoignes, and grandson of William d'Aubigny. He was of brother of Oliver d'Aubigny, Alice d'Aubigny, John d'Aubigny, Gunnora de Gaunt, William De Stuteville, Matilda d'Aubigney, Ralph d'Aubigny and Elias d'Aubeny Oliver d'Aubigny married the widow of the leading royalist Philip of Oldcoates in 1221, and later bequeathed land at Enderby in Leicestershire upon his death to the canons of Croxton Abbey, where he was buried. Philip d'Aubigny was the cousin of William d'Albigny, one of the twenty-five executors of Magna Carta in 1215. The d'Aubigny lands of Ingleby and South Petherton remained under their families possession until 1554, when they were granted to John Bourchier, earl of Bath.
