The connection between the Lyon family of Warkworth, Northamptonshire and Warkworth Castle is through the builder of the castle -- Robert FitzRoger 2nd Baron of Warkworth is Sir John de Lyons, III, lV Baron of Fortevlot, Forgandenney & Drumgawknames, Chambe's second cousin 6 times removed:
Sir John de Lyons, III, lV Baron of Fortevlot, Forgandenney & Drumgawknames, Chambe
→ Alice St. Lise
his mother → William St. Lise, of (Warkworth and) Seaton and Thorpe
her father → Sir Richard St. Lise
his father → Sir? Simon St. Lise, (V?)

his mother → Rohese de Clare

his sister → Alice de Vere
her daughter → Robert FitzRoger, 2nd Baron of Warkworth
her son
The ancestry of this Sir John de Lyons, III is all from Warkworth, Northamptonshire. The connection is through his mother, Alice St. Lise
I hope I didn't imply that Warwick Castle, Northumberland, was the "home" or seat of John de Lyon, II (lll) of Warkworth (Northamptonshire).
My intent was merely to demonstrate the blood kinship between the families. Sir John Lyon, IV, Knight, of Glamis and Johanna “Jean” Stewart, Princess of Scots , as members of the royal family of Robert II, King of Scots
"In 1332 the castle passed to Henry Percy, 2nd Lord Percy, who had been granted it by Edward III.[5] At that time the Percy family was emerging as one of the most important in the north of England. The castle and barony of Alnwick remained the Percys’ chief holding in Northumberland throughout the Middle Ages, but Warkworth Castle was their favoured residence until the 17th century.
"Neither the 2nd nor the 3rd Lord Percy appears to have undertaken much work to the castle, but Henry Percy (1341–1408), 1st Earl of Northumberland, transformed it.[6] He was the first great landowner in the North to acquire a noble title, and he almost certainly celebrated this by building the great tower. It is also likely that he established the hermitage at Warkworth."

Robert II, King of Scots is Henry Percy, 1st Earl of Northumberland's third cousin once removed:
Henry Percy, 1st Earl of Northumberland
→ Mary of Lancaster, Baroness Percy
his mother → Maud de Chaworth
her mother → Isabella de Beauchamp, Countess Winchester
her mother → Maud FitzJohn, Countess of Warwick***
her mother → Aveline Fitzjohn, of Ulster
her sister → Gille (Giles) de Burgh, of Ulster
her daughter → Walter Stewart, 6th High Steward of Scotland
her son → Robert II, King of Scots
his son
I don't see how there can not be a connection, being that the princess of Scotland married this man whose family is apparently proven to be from Northamptonshire. Attention to the various coats of arms may be helpful in shedding light on the problem.

I only intended to demonstrate the blood kinships between the Lyons of Northamptonshire and the various owners of Warkworth Castle in Northumberland. Didn't mean to imply that Warkworth Castle in Northumberland was ever owned by or the seat of the Lyons family.
from Wikipedia:
Scottish Branch
Some sources identify the progenitors of the Scottish branch of the family, Clan Lyon, who subsequently became the Earls of Strathmore and Kinghorne,[12] to be members of the Anglo-Norman family who emigrated to Scotland the end of the eleventh century in the retinue of Edgar, son of Malcolm III of Scotland, to fight against his uncle, Donald Bane.[12][13][14][15][16] Subsequent to the victory of Edgar, these members of the family received lands that were later called Glen Lyon in Perthshire,[12] and, in 1105, Roger de Leonne witnessed a charter from Edgar to Dunfermline Abbey.[12]
Other sources identify the progenitor of the Scottish branch as Sir John Lyon, Baron of Forteviot, Forgandenny, and Drumgawan (1289–1348), the son of a member of the Warkworth line,[6] who was born in Scotland. His son was Sir John Lyon, Thane of Glamis (1340–1382), who married a daughter of Robert II of Scotland, for whom he served as Chamberlain of Scotland:
this Sir John Lyon was known as the White Lyon due to his pale complexion.[12][17] His marriage brought him ownership of Tannadice on the River Esky, and he was also granted the barony of Kinghorne. The present Lords of Kinghorne descend from the White Lyon in the direct line.[17] The son of this Sir John (b.1340) was Sir John Lyon (1377–1445), who married a granddaughter of Robert II, and the grandson was Patrick Lyon, 1st Lord Glamis,[6][18] who was a Privy Counsellor and Master of the Royal Household.[17]

So I assume that you dispute the connection between the Lyons of Northamptonshire and Clan Lyon of Scotland.
I really don't know the answer, although I find the whole subject very interesting and feel it worthy of further research by more than one scholar.
I guess the key issue / question is: Was the builder of Warkworth Castle, Northumberland (a descendant of Roger de Leonne of Lyons, France) related to the Lyons of Warkworth, Northamptonshire, whose lands they received as a grant from William the Conqueror?
