His next brother, John, became sixth Lord Forbes, before 30th October 1496, at which date he is witness to a charter. The sixth lord died in 1547. He was thrice married, first, to Lady Catherine Stewart, second daughter of John, Earl of Athole, uterine brother of King James II., and by her he had a son John, who died young, and a daughter, Elizabeth, married to John Grant of Grant; secondly, to Christian, daughter of Sir John Lundin of that ilk, by whom he had two sons and four daughters; and, thirdly, to Elizabeth Barlow or Barclay, relict of the first Lord Elphinstone, killed at Flodden in 1513, by whom he had a son, Arthur Forbes of Putachie, and a daughter, Janet, who was also thrice married.

The elder son of the second marriage, John, the Master of Forbes above mentioned, is stated to have been a young man of great courage and good education, but of a bold and turbulent spirit. He was beheaded for treason, on the 17th of July 1537.

After the execution of the Master, the king (James V.) seems to have been anxious to compensate the family for his severity towards them, by admitting his next brother, William, into his favour. He restored to him his brother’s honours and estates, and in 1539, appointed him one of the gentlemen of his bedchamber. This William succeeded his father in 1547, as seventh Lord Forbes, and died in 1593. He had married Elizabeth Keith, daughter and coheiress, with her sister, Margaret, Countess Marischal, of Sir William Keith of Inverugie, and had by her six sons and eight daughters. The sons were, John, eighth Lord Forbes; William, of Foderhouse; James, of Lethendy: Robert, prior of Monymusk; Arthur of Logie, called from his complexion, “Black Arthur;” and Abraham, of Blacktoun.

John, eighth Lord Forbes, was one of the five noblemen appointed by commission from the king, dated 25th July 1594, lieutenants of the northern counties, for the suppression of the rebellion of the popish Earls of Huntly and Errol. His lordship was served heir to his mother 13th November 1604, and died soon afterwards. He had married, while still Master of Forbes, Lady Margaret Gordon, eldest daughter of George, fourth Earl of Huntly, and had, with a daughter named Jean, a son, John, who, being educated in the faith of his mother, entered a religious order on the continent, and died without succession. This lady Lord Forbes repudiated, and in consequence a sanguinary contest took place in 1572, in the parish of Clatt, Aberdeenshire, between the two rival clans of Forbes and Gordon. The latter, under the command of two of the earl’s brothers, attacked the Forbeses, within a rude intrenchment which they had formed on the white hill of Tillyangus, in the south-western extremity of the parish, and after a severe contest the Gordons prevailed, having carried the intrenchment, and slain the Master’s brother, “Black Arthur.” The pursuit of the Forbeses was continued to the very gates of Druminner, the seat of their chief. A number of cairns are still pointed out where those slain on this occasion are said to have been buried. The eighth Lord Forbes took for his second wife, Janet, daughter of James Seton of Touch, and had, besides Arthur, ninth lord, another son, and a daughter.

Arthur, ninth lord, married on 1st February 1600, Jean, second daughter of Alexander, fourth Lord Elphinstone. He was succeeded by his only surviving son, Alexander, tenth Lord Forbes, who fought against the imperialists under the banner of the lion of the north, the renowned Gustavus Adolphus of Sweden, in whose service he attained the rank of lieutenant-general, and won for himself a high military reputation. On his return home, he had a considerable command in the army sent from Scotland to suppress the Irish rebellion in 1643. He afterwards retired to Germany, where he spent the remainder of his days. He was twice married—first, to Anne, eldest daughter of Sir John Forbes of Pitsligo, by whom he had, besides several children, who died young, a son, William, eleventh Lord Forbes; and secondly, to Elizabeth, daughter of Robert Forbes of Rires, in Fife, and by her had a large family.

William, eleventh Lord Forbes, died in 1691. He was thrice married, but had issue only by his first wife, Jean, a daughter of Sir John Campbell of Calder.

His eldest son, William, twelfth Lord Forbes, was a zealous supporter of the revolution. In 1689 he was sworn a privy councillor to King William. He died in July 1716. By his wife, Anne, daughter of James Brodie of Brodie, he had three sons and one daughter.

William, the eldest son, thirteenth Lord Forbes, married, in September 1720, Dorothy, daughter of William Dale, Esq. of Covent Garden, Westminster. He died at Edinburgh 26th June 1730. He had a son, Francis, fourteenth lord, who died in August 1734, in the thirteenth year of his age, and four daughters, one of whom, Jean, was married to James Dundas of Dundas, and another, the youngest, Elizabeth, married John Gregory, M.D., professor of the practice of medicine in the university of Edinburgh, and was the mother of the celebrated Dr James Gregory.

James, second son of the twelfth lord, succeeded his nephew, as fifteenth Lord Forbes, and died at Putachie, 20th February 1761, in the 73d year of his age. He married, first, Mary, daughter of the third Lord Pitsligo, widow of John Forbes of Monymusk, and grandmother of the celebrated Sir William Forbes of Pitsligo, baronet, and had a son, James, sixteenth Lord Forbes, and three daughters; secondly, in July 1741, Elizabeth, daughter of Sir James Gordon of Park, baronet.

James, sixteenth lord, died at Edinburgh 29th July 1804, in the 80th year of his age. By his wife Catherine, only daughter of Sir Robert Innes, baronet, of Orton and Balvenie, he had four sons and two daughters.
