The records of the Abernethy line are very meager for several generations. All record of the means by which the Abernethies acquired the estate of Saltoun in East Lothian, or the date at which it came into their possession, has unfortunately perished, but they appear to have held it before the time of this Sir William Abernethy, first of Saltoun (1261 - 1296) ; and he probably obtained it, as well as Glencorse (which had belonged to his elder brother Hugh Abernethy) and Ulkestone or Ugistone, in Berwickshire, as his appanage . . .; (p. 29) Sir William Abernethy granted a donation of two marks out of the profits of his mill at Ulkestone in Lauderdale, to the Abbey of Dryburgh, in 1273 (Cart.

Dryburgh, No. 312). And at pages 42, 43: William Abernethy, second Lord Saltoun, resigned the whole of his possessions into the hands of King James the Thrid . . . 28th January 1463 (Reg. Mag. Sig., Lib. vi. No.’s 79, 114), and the King thereupon granted him a new charter of them. The same ceremony was repeated on the 4th of August in the next year, probably on account of the barony of Corncairn having been omitted in the former charter. These estates consisted of Rothiemay and Corcairn, Banffshire; Rethie, Forfarshire; Glencorse, Edinburgh; Plenderleith, Roxburghshire; Saltoun, Haddingtonshire; Dalgetty, Fife; Dalders, Stirlingshire; and Lyelstoune and Ugistoune, in Berwickshire, all consideral properties . . . And the lands of Ogston in Haddington and Berwick shires are mentioned in the Registrum Sigilli Magni (Paul), in the following places, viz :- . . .
