Leddel family.

William Leddel, Jr., the son of William Leddel, a French naval surgeon who settled in Elizabethtown, New Jersey, was born in 1747. Upon his father's death in 1766, William Jr. moved to Mendham, New Jersey and apprenticed himself to Dr. Ebenezer Blachy. He established himself as a physician and practiced in Mendham for the remainder of his life. Leddel was also active in military matters, serving in the Revolution, the Whiskey Rebellion, and the War of 1812. He served two terms as Morris County's sheriff from 1783-1785, tried small cases before the Justices of the Peace, and at some point either acquired or built and sawmill in southern Mendham on the upper branch of the Passaic River in Jockey Hollow. This mill was replaced by a larger sawmill, woodturning mill, and gristmill, known as Leddel Mill, and seems to have remained in the family for a number of generations.

John W. Leddel, the son of Phebe and William Leddel, was born in Mendham around 1784. He studied medicine under his father's guidance and started practicing in his hometown at the age of eighteen. Like his father, he practiced medicine in Mendham throughout his lifetime. In 1805 he married Jemima Wills (d.1865), the daughter of Samuel Wills, and together they had six children.
