 The first Silverthorns to come to North America seems to have arrived and settled in New Jersey (and Virginia) well before the American Revolution.The New Jersey branch lost all of their land holdings since they were 'loyalists' and came to Canada, receiving land grants via the United Empire Loyalist grants.Although there is no 'official' coat of arms for this surname, there is a very old 'unofficial' one (from the Bristol/Bathe area of Wiltshire County, England) that often surfaces.
