ACKERS.  (Anglo-Saxon).  Camden derives this surname from the Latin Ager, "a field."  Most authorities, however, make it a Saxon name, derive it from ac/ake "oak," and render it "the place of oaks," or "oak-man."

The termination er, in many nouns has the same signification as the Latin vir, a man—as Plower, i.e., Plowman; Baker, Bakerman.

Like oak, the first Acker might have been firm and unyielding in his disposition, or he might have used or sold acorns.
