He claimed to have suffered serious losses, amounting to £12000, as a result of his support for the Glorious Revolution and petitioned the English Parliament for redress.
He was an Irish Privy Counsellor and Lord Justice of Ireland 1709–10; a letter from Marlborough makes clear that this appointment was his doing, a sign of his personal regard for Ingoldsby.
He became rich enough to buy Carton House, ancestral home of the Earl of Kildare, and was recommended for a Peerage shortly before his death.
Ingoldsby died in January 1712 and was buried after an impressive State funeral in Christ Church Cathedral.
He wasted most of his father's fortune on high living in London, and after his death, his heirs were forced to sell Carton back to the Earl of Kildare in 1738.
