Having an unusual name like "Dewsnap" has made me want to find out a little bit more. Here are my findings: The name "Dewsnap" is derived of the Norman race and appears in England from 1066 AD. The first record was found to be in Cheshire and derived from Thomas de Deuysnape (1086 AD- Domeday book compiled)and gave numerous spellings to the name such as Dewsnap;Dewsnop;Dewsnape;Dewsnappe;Deusnape and many others. The Normans were commonly believed to be of French origin but in fact they were of Viking origin through Thorfinn Rollo who invaded Northern France around 910 AD. Duke William who invaded and defeated England in 1066 was directly decended from Thorfinn Rollo. The name "Dewsnap" emerged as a notable family name in Cheshire where they were seated at Cheadle and Mottram in 1369 AD. The coat of arms for the family name is 3 hammers. With time the name expanded into Scotland, North America, Canada, Australia and New Zealand.
If anyone can add to this history I would be very grateful.
