Just north of the convent grounds is the site of the estate of Berleith, which had been built by Henry Threlkeld. He had, in 1751, married Mrs. Mary Hopkins, a daughter of Dr. Gustavus Brown of Maryland, and widow of Reverend Matthew Hopkins. Henry Threlkeld died in 1781, his widow in 1801. Their one child, John, was married in 1787 to Elizabeth Ridgely, of Maryland. Two years before his marriage he visited England, one object of his trip being to secure a legacy which he converted into gold and brought back with him. He landed in England at Dover, which he described as being "about the size of George Town," the voyage having taken nearly two months--from October 6th to December 3rd. In his journal he wrote of having gone to the House of Commons to hear "Mr. Pitt open the budgett, Mr. Fox followed, and then Mr. Sheridan replied to Mr. Pitt." Of John Threlkeld, an old paper states that "he was well and very widely known as a fine scholar and a man of great benevolence." He was mayor of George Town in 1793 and a personal friend of Thomas Jefferson. He was remembered as a handsome figure on horseback, even in his late years, and his love of following the hounds is a family tradition. The comments made by him in this connection during his stay in England are interesting. After describing the journey by coach past fine estates with "one-half the fields as green as spring with grass," he added, "and but one horse have I seen in the course of thirty miles at pasture, and here I must take notice of their boasting in America of their hunters leaping the five-bar gates." He goes on to explain how the measurements were taken, and concludes, "but still their horses vastly surpass ours." John and Elizabeth Threlkeld had four children, but the only son died in infancy, so the name disappeared, and the family is represented only by the descendants of their daughter, Jane, who married John Cox. [Illustration: COLONEL JOHN COX] Chapter IX _Along First Street (N) from Cox's Row to High Street (Wisconsin Ave.)_ On the northeast corner of First Street (N) and Frederick (34th) Street stands the row of houses which John Cox built. Colonel Cox was for many years most prominent in all the affairs of Georgetown, serving as its Mayor longer than any other one man from 1823 to 1845--22 years. John Cox was of English descent. He was born in 1775 during the Revolution, was the youngest of four children, and being left an orphan as a small child, was raised by an uncle who was a banker in Baltimore. He later lived for a while in Philadelphia, and from there came to Georgetown. He first married Matilda Smith, a sister of Clement Smith, well known as the first cashier of the Farmers' & Mechanics Bank, later its president. They had three children, one of whom was named Clement. By his second marriage to Jane Threlkeld he had seven children.
