[1913 Webster]

friend", "Good sir", "Mister;" -- sometimes used
ironically. [Obs.]
[1913 Webster]

[1913 Webster]

[1913 Webster]
Say ye to the goodman of the house, . . . Where is
the guest-chamber ? --Mark xiv.
14.
[1913 Webster]
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.
