Books on name origins interpret Geer as a Middle-English descriptive name meaning Gerish ie: quick to temper etc but I disagree. The evidence uncovered so far seems to point to a place-name origin...view the evidence below.
According to my Dutch contact GEER is a common Dutch name but the Van der Geer family traces its history back to a piece of marshy wetland near the river Drecht 25k south of Amsterdam. The name GEER also refers to land &/or woods etc.

My thanks to Leo Van der Geer for this info

CORNWALL: 2 sites are in St.Martin in Menage, on the south side of the Helford river. GEAR is a very large univallate hill slope enclosure (Iron-Age), the largest single-banked enclosure in Cornwall. The field name GEAR is found all over the county and the origin of the name is the Cornish place-name element KER meaning a fort or round, usually a univallate enclosed settlement dating back to the Iron Age/Romano-British period. The Cornish "KER" can be found in place names such as CAER, GARE, CAR etc, and as a field name GEAR when it usually refers to a field near or containing  a round.
