I JUST FOUND OUT THAT YOUR LAST NAME SOMETIMES INDICATES WHAT YOUR FAMILY DID IN THE PAST SO I SEARCHED MINE UP HERES WHAT IT GAVE ME:; THE NAME MAXFIELD IS A BOY'S NAME OF ENGLISH ORIGIN MEANING "MAC'S FIELD". THIS NAME MAY BE RELATED TO THE LATIN MAXIMUS, WHICH MEANS "THE GREATEST," OR TO A BRITISH LANDOWNER'S NAME, BUT FOR MOST MODERN PARENTS, IT'S ONE OF SEVERAL WAYS TO GET TO SHORT FORM MAX.
