Early Origins of the Diyel family
The surname Diyel was first found in Lanarkshire (Gaelic: Siorrachd Lannraig) a former county in the central Strathclyde region of Scotland, now divided into the Council Areas of North Lanarkshire, South Lanarkshire, and the City of Glasgow, where they were officially seated from the year 1259 on the lands of Dalyell meaning "the beautiful meadow" on the banks of the River Clyde.
They are descended from a Norman noble who entered England in 1066 and was granted lands in England but was invited north by King David of Scotland about the year 1150, who granted him the lands of Dalyell.
"It is said to have given name to the family upon whom the barony of Dalziel was bestowed by Kenneth II., in recompeuse of some exploit performed by them in the service of that monarch. " 
Dalzell House, a historic house in Motherwell, North Lanarkshire was built by the Dalzell family in the 15th or early 16th century on lands they had held since the 13th century. Sir Robert Dalzell forfeited these same lands around 1342, for residing in England without the King's consent, but they were restored through marriage in the 15th century.
The House is said to be haunted by three female ghosts all in different colored attire: green; white; and grey. The site was re-developed in the 1980s to be private apartments after falling into disrepair from the 1950s onwards.
Hugh the Dull (1294-c. 1346) was Lord of Douglas, a Scottish nobleman and cleric.
