William Doyle, son and grandson of Edward Doyle, was born in Bucks County about the year 1720. In 1745 he petitioned the court for recommendation to the governor for a license to keep a "house of entertainment" in New Britain Township near the crossing of the two great roads across the county, at the present site of Doylestown, and his petition was granted and a license issued. He continued to keep the inn on the New Britain side of the line until 1752, when he purchased two acres covering the present site of the Fountain. House then in Warwick township, and the following year was licensed to keep his inn at that place and regularly conducted the old hostelry there from which the town took its name until 1775, when he sold it and removed to Plumstead Township, and is supposed to have followed some of his children outside of the county soon after; a theory that seems to be borne out by the fact that there is no further record of him in Bucks County after about 1785, and no probate record of the settlement of his estate in the county of his birth. The little hamlet that grew up about his tavern known first as "Doyle's Tavern," a noted stopping place for travelers in colonial times traveling from the Delaware to the Welsh settlements in Montgomery county and from Philadelphia to the "Forks of the Delaware," now Easton, came in the beginning of the revolutionary war to be known as "Doyle Town," and being the geographical center of the county became the county seat in 1812.
William Doyle married first about 1742, Martha Hellings, probably his second cousin, as Elizabeth Dungan, a sister of his grandmother, married Nicholas Hellings. She was at least a daughter of Nicholas Hellings of Newtown, and is mentioned in his will in 1745. William Doyle married (second) about 1775 Olive Hough, widow of John Hough and daughter of Hezekiah Rogers of Plumstead Township, Bucks County. No authentic list of the children of William and Martha (Hellings) Hough is obtainable, as they seem to have left the place of their nativity on reaching manhood and womanhood. Two at least of his sons, Samuel and William, found homes in Northumberland County soon after the close of the Revolutionary War.
William was commissioned sergeant of Captain Thomas Robinson's ranging company in that county, February 10, 1781; the lieutenant being Moses Van Campen, the celebrated Indian fighter. This William Doyle became a colonel in the army operating against the Indians on the frontier in the period following the revolution and up to the second war with Great Britain. He served under General Harrison at the battle of Tippecanoe, and was brevetted brigadier-general for conspicuous bravery in that action. He died soon after the close of the war of 1812-14, and was buried at Fort Meigs, Ohio. The town of Doylestown, Ohio, was so named in his honor.
Samuel Doyle, the grandfather of Lemuel H. Doyle, was born in Bucks County in the year 1752. He served as a soldier during the Revolutionary War, during the latter part of which he was a member of Captain Thomas Robinson's ranging company from Northumberland, and was a friend and associate of Moses Van Campen, the noted Indian fighter who commanded the company as lieutenant in many expeditions against the Indians of the frontier. He obtained a patent for 400 acres of land in Point Township, Northumberland County, where he resided until about 1794, when he formed one of a colony of Pennsylvanians that settled at Painted Post, later called Bath, Steuben County, New York, where he died in 1817. He married Mary Arbor, who was born in Monmouth County, New Jersey, and died at Bath, New York, in 1836, at the age of eighty-four years.
