Sir Adam Gordon of that ilk: apparently had, with an elder son (Sir John of that ilk; imprisoned Durham 1346 [Battle of Neville's Cross], released 1357; had confirmatory charter of Strathbogie 1376; died c1395 and by two illegitimate sons (John/Jock Gordon , of Scudargue, and Thomas Gordon, of Ruthven) was ancestor of Gordon's in Mar, Buchan, and Strathbogie. [Burke's Peerage]
Burke's Peerage indicates that Sir Adam, John's father mentioned above, not John himself, is the father of Adam the 11th Laird de Gordon. See notes under Adam 7th Laird for reason why I do not follow Burke's in this.

Sir John Gordon, his great-grandson, got a new charter from King Robert the Second of the lands of Strathbogie, dated 13th June 1376. He was slain at the battle of Otterbourne in 1388. His son, Sir Adam, lord of Gordon, fell at the battle of Homildon, 14th September 1402. By his wife, Elizabeth, daughter of Sir William Keith, great mareschal of Scotland, he had an only child, Elizabeth Gordon, who succeeded to the whole family estates, and having married Alexander Seton, second son of Sir William Seton of Seton, ancestor of the Earls of Winton, that gentleman was styled lord of Gordon and Huntly. He left two sons, the younger of whom became ancestor of the Setons of Meldrum.
