While I couldn't locate a specific reference source for the meaning of the surname "Garris", I'm going to say that this appears to be a variation of the surname "Garrison" (much as "
Harris " is a variation of "
Harrison ").
Garrison (and most likely Garris) means "son of
Gerard (or son of
Gerald )". Both
Gerard and
Gerald were personal names introduced into England by the Normans.
