"Mr. Thomas Bolton, Trooper,' whether or not related to Major Francis bolton of the County Waterford family, in whose troop of horse he served at Londonderry, was perhaps the father of three men in County Derry and County Antrim who appeared a generation later in the records: Thomas, born about 1645, James about 1650, William, born about 1652. He was a sergeant in the British Army, stationed at Londonderry, when he was recorded at Templemore Cathedral as buried 1 Nov. 1684 A muster roll of Ulster for 1630 still exists. Subsidy rolls for 1664-68 were searched, and Hearth Money or Chimney Tax Rolls for 1663-69. In 1740 and 1766 records of Protestant householders were made; that for 1740 is an invaluable compilation, but not helpful in determining relationships. There is a poll book for 1806 and a census for 1821, with much genealogical detail; also Freehold Registers for the early years of the same century. The files of marriage licenses, deeds, and wills kept in Dublin have been destroyed, but not before Mrs. A. S. Wilkinson and Miss Gertrude O'Farrell had copied Bolton marriages for 1630-1857, and also several deeds and wills of which the substance has been incorporated in these pages. Church records are fragmentary and have not been helpful.
