Note: In the early colonial records of New England, the term goodman is frequently used as a title of designation, sometimes in a respectful manner, to denote a person whose first name was not known, or when it was not desired to use that name; in this use it was nearly equivalent to Mr. This use was doubtless brought with the first settlers from England.
