Where did the last name Granger originate and what is its Cajun French meaning?

Quote from the Related Link: "(Origin Saxon) One who superintended a large farm or Grange." If a name comes from one language, it has no meaning in another language that it does not come from, unless the name is also used in some form in that language. An example: José is the Spanish form of the name Joseph. Therefore its meaning is the same in both languages. But in the case of the name Granger, it has no translation in Cajun French that I am aware of; therefore it has no "meaning" in Cajun French other than its original Saxon meaning.
