Philadelphia a few months later, as he attended a meeting of the Trustees on 31 October, and again his presence is recorded at the three meetings in March 1777. This would seem to refute the statement which has been accepted that he returned to Philadelphia on the entrance of the British troops in September, 1777. We find him also at the meetings of the Trustees in February, March, May, and June 1779. He died 6 September, 1780; and it is believed his death occurred in Philadelphia, or at Mount Airy. By a codicil to his will dated 1 December, 1779 he freed all his slaves.
Chief Justice Allen married 16 February, 1734, Margaret only daughter of Andrew Hamilton, the Councillor, the most eminent lawyer of his time in Pennsylvania, who died in 1741. Her only brothers James and Andrew Hamilton were also Councillors, and the former was Lieutenant Governor of the Province from 1748 to 1754 and died unmarried. Andrew was elected a Trustee in 1754 of the Academy, in the vacancy made by the death of Thomas Lawrence. His second son William Hamilton who was born in 1745 was the builder of the beautifully located and well known Woodland Mansion, near the University Buildings, where he died in 1813. Of William and Margaret Allen’s children, besides Anne who married John Penn, there was another daughter Margaret who married in 1771 James DeLancey eldest son of James DeLancey, Chief Justice and Governor of New York, whose second son John Peter DeLancey was the father of the Rev. William Heathcote DeLancey, D. D., Provost of the University of Pennsylvania from 1828 to 1833. Of their three sons, Andrew married Sarah Coxe, granddaughter of Tench Francis, and was himself a Councillor in 1770, but becoming a loyalist, as was his father, went abroad and died in London in 1825; and James, whose wife was a granddaughter of Thomas Lawrence the Councillor, who died in 1778. Both Andrew and James Allen were graduates of the Academy in the class of 1759.
