Chronicle of the Yerkes Family: With Notes on the Leech and Rutter Families, by Josiah Granville Leach
          Harman Yerkes (Herman2, Anthony1), fourth son and fifth child of Herman Yerkes by his wife Elizabeth Watts, was born in the Manor of Moreland, Montgomery (formerly Philadelphia) County, Pennsylvania, 18  January, 1720; died there, 29 November, 1804. 
          He began his business  career as a farmer and miller. From 1752 until 1755, he engaged in  mercantile pursuits at Plymouth, but returned to farming the latter  year, and continued therein until 1788. He was a large land-owner. His  first real estate purchase was made when he was but twenty-six years  old, and consisted of a tract of one hundred and thirty-seven acres,  located in Plymouth Township, Montgomery County, which he bought, 18  May, 1747, from his brother John, paying him therefore two hundred and  ninety-seven pounds. 
          It is believed that he removed to the land so  purchased at about the time he acquired the same, and that he continued  there until about 1762, when he is supposed to have become a resident  of Warminster, Bucks County, where, in 1765, he was an overseer of the  poor, and where, in 1772, he purchased a plantation of one hundred and  eighty-one acres from Joseph Noble. This tract was situated on the  Street Road at what is now Johnsville Station on the Northeast Pennsylvania Railroad, and on this tract Harman Yerkes established  the first homestead of the Yerkeses in Bucks County, and there some of  his descendants have ever since resided. He returned to the Manor of  Moreland in 1788, which continued to be his place of residence the  remainder of his life.
          Mr. Yerkes was  an active supporter of the War of Independence, and in 1775 he and his  son Edward, who was but eighteen years of age, enrolled themselves in  the Warminster Company of Associators. On 31 July, 1777, he was  recommended to the Executive Council by Judge Henry Wynkoop to look  after billeting the poor. It is probable that his military service was  with the militia only. On more than one occasion the British troopers  from Philadelphia were his unwelcome visitors, and his family was  subjected to the actual terrors and trials of grim war. In this  connection Judge Harman Yerkes, of Bucks County, has contributed the following item:
          
            His wife, Mary Clayton, proved herself worthy of the duty of taking  charge of a young family in such times, as is shown by the following  incident, which the writer heard related from the lips of one (Stephen  Beans, then a small boy) who was present." The house then occupied by the family stood where the smaller end of  the present homestead now stands. It contained a sitting-room and  kitchen on the first floor, with an out attachment used as quarters for the slaves. The second floor was divided into convenient rooms by plain board partitions.
            
           The battle of Crooked Billet fought in 1778, began less than two  miles away, and the retreat, or rather rout, of the Americans drifted  directly over the adjacent lands. Some of the most harrowing scenes of  that dreadful butchery occurred within sight of the Yerkes homestead. 
          "The  narrator of the story lived at the next place north, on the Street  Road, and, the men of the neighborhood being away at the scene of  strife, or in concealing the horses and cattle, he [Beans] accompanied  his mother to the Yerkes place at the  first alarm. While the two women and children were in the sitting room,  an American soldier hastily ran into the house, coming from the south  side, and took refuge under a bed which stood in the northeast corner  of the room. He stated that he was being pursued by the enemy, and in  much alarm asked that his place of hiding be concealed. 
          Mrs. Yerkes told  him he would not be safe there, but that by going out of the back door  he could put the house between him and his pursuers, and might reach  the next place, where there was a large pile of buckwheat straw, in  which he could hide himself. He obeyed her directions, and in a very  short time four British soldiers came in the opposite door and inquired  for him. The ladies protested that he was not there. The soldiers then  looked under the bed, searched the up-stairs rooms, and, after  maliciously sticking their bayonets through the bed-clothing, continued  the pursuit. 
          "The  American afterwards returned and thanked the ladies for his  deliverance, and stated that the British had trampled over the straw  and thrust their bayonets far into it, but fortunately without touching  him. They spoke of setting fire to it, but owing to some alarm,  abandoned the idea and departed."
          The religious affiliations of Harman Yerkes are  matters of some interest to his descendants. His earliest church  connection was, probably, either with the Low Dutch Church, in which  faith his father was no doubt born, or with the Baptists, the faith of  his mother, but on the eve of his first marriage he identified himself  with the Society of Friends, his first wife being of that persuasion. 
          After this, his speech and manners are said to have conformed to the  custom of the Friends; nevertheless, his second and third marriages  were performed by Baptist clergymen, and he seems to have become a  member of the Southampton Baptist Church, Bucks County, as he was one  of the committee of that church, in 1772, for the building of a new  meeting-house, and was buried in the graveyard of the same. These  latter facts suggest the strong probability that shortly before his  second marriage he attached himself to the faith of his mother, and of  his distinguished grandfather, the Reverend John Watts. 
          His death is thus recorded in the American Daily Advertiser, under date of 7 December, 1804:
          
             Died, in Moreland Township, Montgomery County, on the 29th of November, Mr. Harman Yerkes, in  the 85th year of his age, and on the 2nd inst his remains were  interred in the Baptist burial-ground, at Southampton, followed by a  numerous train of relatives and friends. In him was united the tender  husband, the affectionate father, and the steady friend. 
            Yes, he must die! the nearest friend must part; 
              The Victor Death, excepts not of a claim; 
              And though the stroke may crush a kindred heart 
              He heeds it not,—to supplicate is vain! 
            He  has gone, his spirit has flown to regions of everlasting bliss; but  long will he exist in the hearts of those whom he hath left  behind,—yea, until time with them shall be no longer, until they like  him shall be no more.
          
          He married (1), at Plymouth Meeting-House, 22 March, 1750-51, Mary, daughter of Edward Stroud, of Whitemarsh. She died circa 1771,  and 
          he married (2), 30 September, 1773, Mrs. Mary (Houghton) Clayton,  widow of Richard Clayton. She died in 1785, and bequeathed a sum of  money to the Southampton Baptist Church for building a wall around its  graveyard, with which church she was actively identified, and by whose  pastor, Reverend Jonathan Blackwood, she was married to Mr. Yerkes. 
          He  married (3), 28 March, 1788, Mrs. Elizabeth (Ball) Tompkins, widow of  John Tompkins. She died in 1819. After this marriage Mr. Yerkes removed  to his wife's home, on the Old York Road, in Moreland, where the "widow" Tompkins kept an inn and store, the management of which now fell  to Mr. Yerkes.
