A surname, most famously associated with Millard Fillmore, the 13th President of the United States who served in the 1850s.
From Old English 'fill' (to fill up) and 'moor' (an open area of land), originally a place name meaning 'clearing where streams fill up' or similar. Later became a surname.
Millard Fillmore is one of the least-remembered U.S. presidents, which is actually interesting because he's often forgotten despite making significant political decisions during America's slavery crisis!
