**** Narelle Smith of Victoria, Australia, has kindly provided much valuable information on the Simpson family from the generation of Samuel Simpson and earlier.
Narelle is a descendant of William Simpson 1768 - 1837 from his first marriage to Mary Cornfield through their son George.
Regarding the Simpsons an excellent website about the family history is http://simpsonhistory.com/originsimpson.html
The Simpsons were an old Anglo-Saxon family living initially in south-east of England who later (under pressure from the invading Normans) extended north into the midlands then northern counties of England and to the border country of Scotland - where they came into affiliation with the Fraser clan. In the Scottish lowlands they tended to live around Fifeshire and Peebles in the lowlands. There are also indications of Simpsons at Banff in Aberdeenshire.
To quote from the website: http://simpsonhistory.com/originsimpson.html
"The family name Simpson emerged as a notable English family name in the county of Buckinghamshire, where they were descended from Archil, a Saxon lord, living at the time of King Edward the Confessor, about 1050 AD. Even after the Conquest this family held many lands, including the manor of Clint in Yorkshire. In the 12th century this branch called themselves de Clint. Simon, son of William de Clint, adopted the name Simpson to distinguish himself from the de Clints. From the 14th century his family became known as Simpson. They flourished and moved north into Scotland into Fifeshire at Brunton where they became affilated with the Fraser clan."
