Gattis is mainly a surname-derived name, probably from Germanic or English family roots with uncertain exact literal meaning. That uncertainty is part of the surname-name style: the focus is less on a transparent dictionary definition than on the inherited weight of a family line.
As a given name, Gattis feels sturdy and a little old-fashioned in the best way. It has the sound of a name that could belong to a ledger, a byline, or a family tree, which gives it a grounded and slightly formal character. Its rarity makes it feel distinctive without trying too hard.
