John McIlvain (1815), son of John and Lydia (Barnard) McIlvain, was born in Ridley township, in 1765, in the house still standing in Leiperville, owned by his father, where after midnight of September 11, 1777, Washington repaired to sleep, when his defeated army at Brandywine had gathered back of Chester and eastward of Ridley creek. In 1807, he was Director of the Poor. John McIlvain, the younger, and his brother, Jeremiah McIlvain, father of Spencer McIlvain, were in partnership in operating a saw mill and tan yard at the present Leiperville. In 1826, the tan yard was reported as having forty vats and four leaches.
