   User ID: M591.

  General Notes:

"William, third Lord Borthwick, was knighted in his father's lifetime. On 20 September 1484 he was one of the guarantees of a treaty with England. He was one of the Lords Auditors in 1484 and 1485, and in the latter year Master of the Household to James in. He was witness to a charter by the King on 28 May 1488, a few days before His Majesty's death at Sauchie, and on the Committee of Causes 1488-91, and the Council of James IV. and the Privy Council 1489."

from Scots Peerage (vol 2) ¹

William married Mariota DE HOPPRINGILL after 21 November 1458.¹ (Mariota DE HOPPRINGILL was born about 1453.)

  Marriage Notes:

"On 21 November 1458 the first Lord obtained a gift under the Great Seal of the marriage of Mariota de Hoppringill of that Ilk, from which it has been reasonably inferred that she became the wife of his son, now under notice."

from Scots Peerage (vol 2)

Note:

Given that Mariota de Hopringill was a minor in 1458, it might be equally reasonably inferred from the surrounding chronology that she became the wife of the grandson, rather than the son, of the first Lord Borthwick. ¹
