The Worcester Registry of Deeds bears ample evidence that many farms in "the north part" of the town, where the Scotch-Irish were specially located, and where the "Old Fort" stood in which they sometimes worshipped, changed hands in 1737 and in the years immediately following. John Gray, for example, and each of three sons of his, made significant conveyances of land in Worcester in that interval; and it is quite noticeable that the name of John Clark, the first to sign the petition to the town of Worcester for exemption from church taxes in behalf of himself and fellow signers, stands prominent a couple of years later among the first settlers of the Scotch-Irish town of Colerain, fifty miles to the northwest of Worcester, so named from the old Ulster town on the Bann. The Morrisons, Pennells, Herrouns, Hendersons, Cochranes, Hunters, Henrys, Clarks, McClellans, McCowens, Taggarts, and McDowells, many of whom had been previous settlers in Worcester, were the chief families in this frontier and Presbyterian town, now on the border of Vermont.
