In the year 1639 Percival Lowle, or Lowell, a merchant of Bristol, England, landed at the little seaport town of Newbury, Mass. We generally speak of a man's descent. In the case of James Russell Lowell's ancestry it was rather an ascent through eight generations. Percival Lowle's son, John Lowell, was a worthy cooper in old Newbury; his great-grandson was a shoemaker, his great-great-grandson was the Rev. John Lowell of Newburyport, the father of the Hon. John Lowell, who is regarded as the author of the clause in the Massachusetts Constitution abolishing slavery.
