Boyd made himself Governor to the king, his son married the king's eldest sister, Mary, and became Earl of Arran.

But brief was the triumph of the Boyds.
In 1469 James married Margaret of Norway; Orkney and Shetland were her dower; but while Arran negotiated the affair abroad, at home the fall of his house was arranged.

Boyd fled the country; the king's sister, divorced from young Arran, married the Lord Hamilton; and his family, who were Lords of Cadzow under Robert Bruce, and had been allies of the Black Douglases till their fall, became the nearest heirs of the royal Stewarts, if that family were extinct.

The Hamiltons, the wealthiest house in Scotland, never produced a man of great ability, but their nearness to the throne and their ambition were storm-centres in the time of Mary Stuart and James VI., and even as late as the Union in 1707.
The fortunes of a nephew of Bishop Kennedy, Patrick Graham, Kennedy's successor as Bishop of St Andrews, now perplex the historian.

Graham dealt for himself with the Pope, obtained the rank of Archbishop for the Bishop of St Andrews (1472), and thus offended the king and country, always jealous of interference from Rome.
