There have been two baronetcies created for members of the Haggerston, later Constable Maxwell-Scott family, one in the Baronetage of England and one in the Baronetage of the United Kingdom. Only one creation is extant as of 2008. The Haggerston, later Constable Maxwell-Scott Baronetcy, of Haggerston in the County of Northumberland, was created in the Baronetage of England on 15 August 1642 for Thomas Haggerston, of Haggerton Castle, Northumberland, a loyal Royalist who served as a colonel in the army of King Charles I (for information on the early history of the Haggerston family see Haggerston Castle). The Haggerston were recusant in the 17th century and the estates were sequestered and forfeit to the Commonwealth of England in 1649 but were repurchased by the first Baronet in 1653. The line of the fourth Baronet failed on the death of the twelfth Baronet in 1972. The title reverted to the line of William Haggerston, second son of the third Baronet and younger brother of the fourth Baronet. In 1746 he inherited estates in Yorkshire from his great-uncle Sir Marmaduke Francis Constable, 4th and last Baronet, of Everingham (see Constable baronets), and assumed the surname of Constable in lieu of his patronymic. In 1758 he married Winifred, daughter of Robert Maxwell, titular sixth Earl of Nithsdale, and assumed by Royal licence the additional surname of Maxwell. Winifred was considered to be the heiress to the Scottish lordship of Herries of Terregles held (de jure) by her father. Constable-Maxwell built a new house at Everingham Park on the Constable estate in Yorkshire.
His grandson, William Constable-Maxwell, managed to claim the lordship in 1848, when the descendants of the fifth Earl of Nithsdale (who had been attainted) were restored in blood by Act of Parliament. His eldest son, the eleventh Lord, died without male issue and was succeeded in the lordship by his eldest daughter (see the Lord Herries of Terregles for further history of this title). In 1874 the tenth Lord's third son the Hon. Joseph married Mary Monica, daughter of J. Robert Hope Scott by his wife Charlotte Lockhart, granddaughter and heiress of Sir Walter Scott, the great author (see Scott baronets). Joseph's eldest son was created a baronet in his own right in 1932 (see below). Joseph's third son Malcolm Joseph Raphael Constable Maxwell-Scott was a Rear-Admiral in the Royal Navy. He was the father of Michael Fergus Constable Maxwell-Scott, who succeeded his kinsman as thirteenth Baronet in 1972. The present Baronet is also in remainder to the lordship of Herries of Terregles, a title held by his kinswoman Jane Kerr, 16th Lady Herries of Terregles.
The Constable-Maxwell-Scott Baronetcy, of Abbotsford in Melrose in the County of Roxburgh, was created in the Baronetage of the United Kingdom on 23 June 1932 for Major-General Walter Joseph Constable-Maxwell-Scott (see above for his family background). The territorial designation was a revival of the title held by his ancestor Sir Walter Scott. Constable-Maxwell-Scott had no sons and on his death in 1954 the baronetcy became extinct.
