The story of the Boyds begins earlier with family in England.
Alan was the son of Flaald, and had a grant in Norfolk, England, 1101. He was Lord of Oswestry, 1105 10 and Viscount of Shropshire. He married Ameline daughter of Waryn the Bald, by Ameria, (grand)daughter of Roger Montgomery, Earl of Arundel.
Their sons:
William Fitzalan I, (Fitz means son of) was Lord of Oswestry and Viscount of Shropshire, 1126, Tante. He married Helen daughter of William Peverel.These are the Fitzalans of The House of Arundel in England.
Walter Fitzalan was Senescal of Scotland, his descendants became the Kings of the House of Stewart.
* Simon Fitzalan was said to be a younger brother of William and Walter, who followed Walter to Scotland. The 1161 charter of the Monastery of Paisley lists Simon, as “Simon frater,” “Walter filis,” “Alan Lapiferi,” and “Regis Sectiac.”
Simon Fitzalan, was from whom the Boyds descend.
Simon Fitzalan’s eldest son was Robert Boyd, called Robert, the Fair, because of his light hair coloring. The Celtic Gaelic word “Buidh” (yellow) is where the name Boyd comes from.
Robert Boyd (1st generation) had a son Robert Boyd (2nd generation), in 1262 in a charter given to Sir John Erskin he is called “Robertus de Boyd Miles”.
Robert Boyd (3rd generation) died about 1300. His son, Robert Boyd (4th generation) is the one who was with William Wallace and William Mac Cairill. Robert Boyd also was a supporter of Robert the Bruce. After the Battle of Bannockburn he was rewarded by Bruce gifts of the land of Kilmarnock, among others.
The oldest son of Sir Robert Boyd (4th generation) was Thomas Boyd (5th generation) in the line. Thomas Boyd’s son was also Thomas Boyd (6th generation) and was called “Dominus de Kilmarnock” (The first Lord Boyd).
