Recently researched 5 Snelling coats-of-arms. 3 are almost exact showing 3 griffins heads erased and a chief ermine (with minor differences in color and 1 with an added insignia). Info from "General Armory." These coats-of-arms are associated with Chaddlewood, co. Devon; Wheatfield, co. Suffolk, co. Surrey, East Horsley, co. Sussex; and the 3rd not identified to any locality. I also recall reading that Dr. William Snelling of Boston (and Chaddlewood) grandfather's coat-of-arms reflected 3 brothers.
