The mill here designated as Captain George Paris' grist mill was formerly known as Hitches, or Rockawalkin Mill, and was on a branch called Cottingham's Creek. The mills and lands adjoining were purchased by Levin Gale in March, 1730/31, and February, 1735/36, from Mary Cordry and William Elgate, respectively, (Somerset Court, Deed Liber O 17, page 299 deed Gale from Cordry; and Deed Liber O 19, p. 26, deed Gale from Elgate).
The Protestant Episcopal, or Church of England, denomination was established in the Province by act of the Assembly June 9, 1692, “for the service of Almighty God and the establishment of the Protestant Religion in the Province.” It provided that “the Church of England should have enjoy all her rights wholly inviolable as now is or hereafter shall be established by law.” That also the Great Charter of England should be observed in all respects. A heavy fine was imposed for breaking of the Sabbath. The county justices were instructed to meet at their respective county houses, giving notice to the principal freeholders to attend, sometime before September 1; then with the advice of those attending, lay out their several counties into parishes. The freeholders of each parish were then to appoint six vestrymen, who with the first money available were to erect a church in each parish. A levy of forty pounds of tobacco was imposed upon each taxable inhabitant to meet the expense of building churches and chapels and to support the minister. The sheriff was allowed five per cent of the levy was making the collections. The vestry was empowered to accept gifts, prosecute claims and to supply vacancies. The four prominent freeholders called to attend the meeting with the justices at the court house on Back Creek with Daniel Hast, William Elgate, William Alexander and Mathew Wallis from Wicomico Hundred; Robert Collier, James Weatherly, John Bounds and Capt. William Piper from Nanticoke Hundred.
