Looking for Gravelstine Cranston of New York and Ontario

I am looking for any information on the family Gravelstine/Cranston.
Abraham Gravelstine changed his name to Cranston. He orginally came from New Yrok then on to Ontario, Canada. He changed his name to Cranston in or around 1851 as the family goes he was defecting from the war. Look for more of the Cranston Family in Ontario.
