Notes:

She may have been the aunt, or great-aunt of Jean Halyburton, who married James douglas, 16th of Cavers (dsp 1780)

Extract from The Scottish Nation, by William Anderson, Vol2, 1867: Pitcur was inherited by Agatha Halyburton, wife of the fourteenth earl of Morton, whose second son, the Hon. Hamilton Douglas, became possessed of it, and according to the entail, assumed the name of Halyburton. On his death in 1784, it went to his aunt, Mary, countess of Aboyne, whose second son, Colonel the Hon. Douglas Gordon, afterwards Lord Douglas Gordon Halyburton, succeeded to it, and on his death in 1841, his nephew, Lord Frederick Gordon, became the proprietor, also taking the name of Halyburton, being the lineal male heir and representative of that ancient family.

But note: Hamilton was most probably a grandson of Agatha, son of the 15th earl of Morton. His birth was in 1763, or later (he was a midshipman, so unlikly to have been any older).

Agatha married James (14th Earl of Morton) Douglas before 1731. James (son of George (13th Earl of Morton) Douglas and Frances Adderley) was born in 1709; died on 12 Oct 1768 in Chiswick. [Group Sheet] [Family Chart]

Oldest son of David Halyburton (d. 1689) of Pitcur by Agnes Wedderburn, prob. da. of Alexander Wedderburn of Tofts and Kingennie, Forfar. m. by 1707, Catherine, da. of Sir John Hall, 1st Bt., MP [S], of Dunglass, Haddington, ld. provost of Edinburgh 1689? 91, 1692? 4, 1s. da.; ? contr. 8 Dec. 1710, Mary, da. of George Drummond of Blair Drummond, Perth., s.p. suc. fa. on reversal of outlawry 1700

The date of Halyburton's death has not been firmly established. Family histories place it around 1742? 3, but his son, Colonel James Halyburton, was served as heir on 17 July 1755. When the colonel, who was himself by all accounts a rather unstable individual, died childless in 1765, Pitcur passed to his great-nephew, Hamilton Halyburton Douglas, son of the 16th Earl of Morton.

James married Mary Drummond on 25 Aug 1709 in Kincardine By Doune, Perthshire, Scotland. Mary (daughter of George (5th of Blair, 1st of Blair-Drummond) Drummond and Elizabeth Ramsay) was born on 21 Mar 1689 in Edinburgh, Midlothian, Scotland; died on 22 Mar 1689 in Edinburgh, Midlothian, Scotland.
