Born in 1857, Sidney Perley was a well-known lawyer in Essex county, Massachusetts. He also wrote books and articles on history, genealogy, and the law. From 1897 to 1909 he published the Essex Antiquarian. These journals include so much valuable information, I've included the links below. Perley died in 1928.
For more articles published by Perley, check out my links to the Essex Institute Historical Collections (EIHC). He also wrote pieces for the New England Historic Genealogical Society (AmericanAncestors.org).
