ter county, Pa., 7 Oct., 17-J2 ; d. in Phihidelphia,
Pa., 2 Feb., 1790. About 1732 his father, George
Duffield, emigrated from Ireland to Pennsylvania,
where he bought extensive lands. The son was
partly educated at Newark, Del., and subsequently
entered Princeton, where he was graduated in
1752. He studied theology under Dr. Robert
Smith, of Pequea, and, after officiating for two
years as tutor in Princeton, was ordained in Sep-
tember, 1761, and took charge of the united
Presbyterian churches in the frontier towns of
Carlisle, Big Spring, and Monaghan, Pa. In 1766
Mr. Duffield made a missionary tour through the
valleys of Pennsylvania, Maryland, and Virginia,
the object of which was to administer the offices
of religion to families scattered throughout that
region, and to establish churches. He warmly
espoused the sentiments of the " New Lights " in
opposition to the " Old Side " party, and encount-
ered much opposition, which was continued after
his removal in 1771 to the 3d Presbyterian
church in Philadelphia, and increased by the fact
that he was a zealous whig. On one occasion his
church was barred against him, and thei'e was such
a disturbance that a magistrate was called to read
the riot act, but he was finally allowed to govern
his charge unmolested. During the Revolution he
served as chaplain and fearlessly shared the dan-
gers and privations to which the army was exposed,
being so hated by the enemy that a reward was
offered for his head. He was also associate chap-
lain with Bishop William White of the 1st Con-
tinental congress. He took an active part in the
organization of the Presbyterian church after the
Revolution, and was chosen the first stated clerk of
the general assembly, which place he held till his
death. The degree of D. D. was conferred upon
him by Yale in 1785. His only published works
