Geer History, Family Crest & Coats of Arms
As we follow the name Geer back through history, we find that the surname is ultimately derived from the Middle English word "geary," meaning "changeable" or "passionate." 
Another source notes "This surname is derived from a geographical locality. 'at the gare' , from residence thereby." 
And another source states "Gear signifies all sorts of wearing apparel and equipments for horses and men, from the Saxon gearrian, to make ready; and the name was probably given to one who took charge of and superintended the gear. John of the Gear, John O' Gear, and at length John Gear."

Allen Atte-gar, was vicar of Elmham, Norfolk in 1356.

A great wave of immigration to the New World was the result of the enormous political and religious disarray that struck England at that time. Families left for the New World in extremely large numbers. The long journey was the end of many immigrants and many more arrived sick and starving.

These emigrant families went on to make significant contributions to these emerging colonies in which they settled. Some of the first North American settlers carried this name or one of its variants:
