Hi Julie, mygggggggrandfather Samuel Keyser from Haverhill,Mass had a son William Keyser (b. March 7th, 1748/49 in Rowley, Mass.) He was married to a Mary Clough. So the above Samuel married a Abigail Harriman in Rowley, Mass. on April 20th, 1742 Samuels father was Timothy Keyser (b.November 23rd, 1683 in Haverhill, Mass.), who married Sarah Hodgkins in Ipswich, Mass. December 10th, 1710. His father was John Keyser (b.1648 Lynn, Mass.),(- died in the Dustin Masacre)who married Hannah Davis (b.December 24th, 1653 in Dover, N.H.), on the 28th of September 1677 in Haverhill, Mass.. And his father was George Keyser (b.November 4th, 1610 in Leighton-Buzzard, Bedford), England, married Elizabeth Holyoke (b.1619 in Tamworth, Warwickshire, England) Maybe this is can help you finding out if it is the William you are looking for !
