The Leache are the descendants of a McLeach family, of Scotland. Three brothers McLeach came to this country. from the Highlands of Scotland about 250 years ago, and settled at Cold Run, Mass. They afterwards removed to Westmoreland, N. H., where, nearly 125 years since, the name was changed, on petition to Parliament, from McLeach to Leach. One of these brothers, Josiah McLeach, whose wife was Sarah Brittain, of Wales, was the grandfather of Zephaniah Leach, the early settler of Waterville.
