Adam de Castlerock  25
Probably of the de Vallibus family
Founder of the SIZERGH LINE of the STRICKLAND FAMILY
The Strickland of Sizergh Family, the name of the Strickland family home, is of Scandinavian origin, and originates from the Scandinavian occupation of England in the 9th and 10th Centuries. Along with a large gift of other lands, Sizergh was granted by Henry II about 1170-80 to Gervase d'Eyncourt (Deincourt), a cadet of the great baronial family of that name settled at Blankney in Lincolnshire. It is situated within the parish of Helsington, but as a separate independent manor. These possessions continued in the Deincourt family for several generations until Elizabeth, great granddaughter of Gervase, became on the death of her brother the sole heiress, and conveyed them all in marriage to her husband, Sir William Strickland in 1239. From that time, this has been the residence of the Strickland family. In earlier times, the family was known as 'De Castlecarrock', and they were descended from the Norman family of Vaux (or De Vallibus), and therefore allied to the family of Gilles, son of Bueth, the original native chieftain holder of Gilsland, near Carlisle. In 1179, Walter De Castlecarrock married, moved to the manor of Great Strickland in north Westmoreland acquired through his wife, and assumed the name 'De Strikeland'. The name meant 'the pastureland of young cattle'. This Walter was later knighted and was the great-grandfather of the Sir William mentioned above. Family members have been found in Parliament in almost every generation until the end of the 17th Century. They have also been involved in other parts of Government, including the military, up to the present time.
