Cooper, S. I. N/A
The crest is that of the Cooper family. Fairbairn's Crests gives it with the lion argent as Cooper of Yorkshire, and Burke's General Armory with the lion proper as Cooper of Painshill, Surrey. There is a genealogy of Cooper of Painshill in Burke's Landed Gentry for 1875, but it contains no S.I. Cooper. Samuel is a common first name in many families of Coopers.
