His eldest son, Gilbert, or Gillebrid, appears to have borne the surname of Buchanan.

Sir Maurice Buchanan, grandson of Gilbert, and son of a chief of the same name, received from Donald, Earl of Lennox, a charter of the lands of Sallochy, with confirmation of the upper part of the carrucate of Buchanan. Sir Maurice also obtained a charter of confirmation of the lands of Buchanan from King David II. in the beginning of his reign.

Sir Maurice de Buchanan the second, above mentioned, married a daughter of Menteith of Rusky, and had a son, Walter de Buchanan, who had a charter of confirmation of some of his lands of Buchanan from Robert the Second, in which he is designed the king’s “consanguineus,” or cousin. His eldest son, John, married Janet, daughter and sole heiress of John Buchanan of Leny, fourth in descent from Allan already noticed. John, who died before his father, had three sons, viz., Sir Alexander, Walter, and John, who inherited the lands of Leny, and carried on that family.

Sir Alexander died unmarried, and the second son, Sir Walter, succeeded to the estate of Buchanan.

This Sir Walter de Buchanan married Isabel, daughter of Murdoch, Duke of Albany, governor of Scotland, by Isabel, countess of Lennox, in her own right. With a daughter, married to Gray of Foulis, ancestor of Lord Gray, he had three sons, viz., Patrick, his successor; Maurice, treasurer to the Princess Margaret, the daughter of King James I., and Dauphiness of France, with whom he left Scotland; and Thomas, founder of the Buchanans of Carbeth.

The eldest son, Patrick, acquired a part of Strathyre in 1455, and had a charter under the great seal of his estate of Buchanan, dated in 1460. He had two sons and a daughter, Anabella, married to her cousin, James Stewart of Baldorrans, grandson of Murdoch, Duke of Albany. Their younger son, Thomas Buchanan, was, in 1482, founder of the house of Drumakill, whence, in the third generation, came the celebrated George Buchanan. Patrick’s elder son, Walter Buchanan of that ilk, married a daughter of Lord Graham, and by her had two sons, Patrick and John, and two daughters, one of them married to the laird of Lamond, and the other to the laird of Ardkinglass.

John Buchanan, the younger son, succeeded by testament to Menzies of Arnprior, and was the facetious “King of Kippen,” and faithful ally of James V. The way in which the laird of Arnprior got the name of “King of Kippen” is thus related by a tradition which Sir Walter Scott has introduced into his Tales of a Grandfather:—“When James the Fifth travelled in disguise, he used a name which was known only to some of his principal nobility and attendants. He was called the Goodman (the tenant, that is) of Ballengeich. Ballengeich is a steep pass which leads down behind the castle of Stirling. Once upon a time when the court was feasting in Stirling, the king sent for some venison from the neighbouring hills. The deer was killed and put on horses’ backs to be transported to Stirling. Unluckily they had to pass the castle gates of Arnprior, belonging to a chief of the Buchanans, who chanced to have a considerable number of guests with him. It was late, and the company were rather short of victuals, though they had more than enough of liquor. The chief, seeing so much fat venison passing his very door, seized on it, and to the expostulations of the keepers, who told him it belonged to King James, he answered insolently, that if James was king in Scotland, he (Buchanan) was king in Kippen; being the name of the district in which Arnprior lay. On hearing what had happened, the king got on horseback, and rode instantly from Stirling to Buchanan’s house, where he found a strong fierce-looking Highlander, with an axe on his shoulder, standing sentinel at the door. This grim warder refused the king admittance, saying that the laird of Arnprior was at dinner, and would not be disturbed. ‘Yet go up to the company, my good friend,’ said the king, ‘and tell him that the Goodman of Ballengeich is come to feast with the King of Kippen.’ The porter went grumbling into the house, and told his master that there was a fellow with a red beard at the gate, who called himself the Goodman of Ballengeich, who said he was come to dine with the King of Kippen. As soon as Buchanan heard these words, he knew that the king was come in person, and hastened down to kneel at James’s feet, and to ask forgiveness for his insolent behaviour. But the king, who only meant to give him a fright, forgave him freely, and, going into the castle, feasted on his own venison which Buchanan had intercepted. Buchanan of Arnprior was ever afterwards called the King of Kippen.”[238] He was killed at the battle of Pinkie in 1547.

The elder son, Patrick, who fell on Flodden field, during his father’s lifetime, had married a daughter of the Earl of Argyll. She bore to him two sons and two daughters. The younger son, Walter, in 1519, conveyed to his son Walter the lands of Spittal, and was thus the founder of that house. On the 14th December of that year, he had a charter from his father of the temple-lands of Easter-Catter.

The elder son, George Buchanan of that ilk, succeeded his grandfather, and was sheriff of Dumbartonshire at the critical epoch of 1561. By Margaret, daughter of Edmonstone of Duntreath, he had a son, John, who died before his father, leaving a son. By a second lady, Janet, daughter of Cunninghame of Craigans, he had William, founder of the now extinct house of Auchmar.

John Buchanan, above mentioned as dying before his father, George Buchanan of that ilk, was twice married, first to the Lord Livingston’s daughter, by whom he had one son, George, who succeeded his grandfather. The son, Sir George Buchanan, married Mary Graham, daughter of the Earl of Monteith, and had, with two daughters, a son, Sir John Buchanan of that ilk. Sir John married Anabella Erskine, daughter of Adam, commendator of Cambuskenneth, a son of the Master of Mar. He had a son, George, his successor, and a daughter married to Campbell of Rahein.
