The name "LAMPLUGH"  had begun to make its appearance in written records as Lamploch; Landploc; Lanplou; and Lumplow.The word 'llan' or 'landa' is Celtic meaning enclosure. The word 'plwyf' is also Celtic for Parish hence 'Llan-plwyf' eventually became Lamplugh.The Anglo - Saxons gave their names to Murton and Kelton. [townships within the parish] These families came from the south and used their farming expertise to settle on the  heavier fertile lands. Most of the' new' early Lake District place names are Old Norse, thus Lamplugh being of Celtic origin is further evidence of its great age.

William de Lancaster was a commander under Henry II in the wars against David Ist of Scotland and helped to recover the Counties of Cumberland and Westmorland which had been ceded to the Scots by King Stephen in 1136. Thomas the son of Gospatrick gave Lamplugh to one Robert who  took the name of Lamplugh [Robert de Lamplo], he also held Holker. He died in the reign of Henry II and is the first of the family recorded in the pedigree. This was certified by John Lamplugh Esq.in 1665 in which he traced twenty four generations.
