Osulf De Havrington

From Ancestry and Descendants of William Harrington or Herrington 1718-1794, page 2:

A century after the beginning of the Norman Conquest of England in 1066, Osulf (Latin, Osulphus), holder of the Manor of Flemingby, appeared in history with a gift of land to the Priory of Carlisle. Osulf's manor was located on the Cumberland coast a short distance north of the Town of Harrington of today. The site of his residence and the hamlet which, no doubt, surrounded it is marked now by the Village of Flimby. It is a residential village with a population of about twelve hundred.

Osulf was undoubtedly of Norman ancestry since his descendants used the ancient Norman shield design shown in the fronticepiece. In addition, large landholdings such as his were held by the Norman conquerors and their descendants.
