Hugh MacDuff, 2nd son of Earl Gillemichel, had 2 sons: Hugh / Aed / Giles, and Orm.

Abbots and lords of Abernethy

The abbots of Abernethy were descendants of Gille Míchéil, Earl of Fife. The abbacy may have been held by Áed (called Hugo or Eggu and other Latinised forms), son of Gille Míchéil,[2] but the abbacy is first attested when Áed's son Orm is confirmed in possession of it by King William of Scotland in the 1170s, in condition for making concessions favorable to the King's new monastic establishment at Arbroath Abbey.[3] The title of Abbot disappears in the sources during the abbacy of Laurence, with the title of dominus predominating:

• Orm de Abernethy (fl. 1170s)
• Laurence de Abernethy (fl. 1190s)
• Hugh de Abernethy (d. 1291)
• Alexander de Abernethy (d. c. 1315)

Following the death of Alexander Abernethy, the title passed to his daughter Margaret who married John Stewart of Bonkyll, who assumed the title, as well as being granted the forfeited Earldom of Angus. https://en.wikipedia.org/wiki/Lord_of_Abernethy

2I. ORM (HUGH 1)

d.c.1185

Orm is listed as son of Hugh and probably succeeded his father as Lay Abott of the Culdee monastery. He witnessed a charter by Ernaldus or Arnold, Bishop of St. Andrews between Nov. 1160 and sept. 1162.(1) Orm also witnessed a charter of William the Lion. (2)

Orm exchanged the lands of Balbirnie with Duncan, Earl of Fife, for the lands of Glendukie and balmeadow in Fife, a transaction confirmed by King William the Lion between 1165 and 1171. Also during this time King William bestowd on Orm, son of Hugh, the lands of Invaryhten reserving to the King the service due for these lands, likewise commanding that any natives and fugitives pertaining to them, be not unjustly detained by other owners. Orm is the first of the family who is found bearing the territorial appellation 'de Abernethy' as it was to him the King William granted the charter of the abbacy of Abernethy between 1172 and 1178 with all the rights as they stood the year and day when King David, the King's grandfather was living, except the £10 lands which the King gave to Henry Revel with the daughter of said Orm; to be held to him and his heirs free of all services and customs except common aid, common hosting, and common carriage, with soc, sac, tol and theme, and infangthef; paying yearly £20 of silver, £10 at the feast of St. John the Baptist and £10 at the feast of St. Bride. he was to have neither pit nor gallows but at two places, Abernethy and Inerarichtin and the King willed that Orm's men of Fife and Gowry should come to the 'mote' or 'pit' of Abernethy and those of his other lands to the mote or pit of Inverarity.(3)

  • A. Gillemichael, 3rd Earl of Fife (d by 07.1136)
    • i. Duncan, 4th Earl of Fife (d 1154)
    • ii.'Hugh (Eoghin) of Fife
      • a. Hugh (Egius) of Fife This Hugh was long identified as father of John of (Wemyss and) Methil, ancestor of the Wemyss family, but according to TSP (Wemyss) that connection has since been disproved as John's father has since been confirmed as Michael of (Wemyss and) Methil whose wife may have been a daughter of Earl Gillemichael.
      • b. Orm de Abernethy (a 1172/3) -- Orm, son of Hugh, is identified in TSP (Saltoun), and also 'Fife (P&H)', as ancestor of the Abernethy family. BP1999 (Saltoun) identifies that Hugh as son of Gillemichael, 3rd Earl of Fife. That claim was not made for BP1934 (Saltoun) so it is assumed that some additional evidence has been found to justify that identification.
    • iii. Ete of Fife J m. Gartnait, Earl of Buchan

• “ The Abbots of Abernethy & Dunkeld” At that time, Áed’s son Orm was officially confirmed as lay abbot of Abernethy Abbey. The Abbots of Abernethy were descendants of Gille Míchéil, Earl of Fife (my 27th great-grandfather). Although the abbacy was first held by Gille Míchéil’s son, Áed, the position was not officially recognized by the state until the 1170s by William “The Lion” of Scotland (my two-times 25th great-grandfather). The hereditary lay abbots in my family were Áed de Abernethy (my 26th great-grandfather), Orm de Abernethy (my 25th great-grandfather), and Laurence de Abernethy (my 24th great-grandfather).
• ON SCHOLASTIC OFFICES IN THE SCOTTISH CHURCH IN THE TWELFTH AND THIRTEENTH CENTURIES. APPENDIX TO PREFACE. Page 63. PDF Not every abbot, it has been seen, was a monk, nor did every abbot always take or receive the name of abbot. It is as ' Horm the son of Hugh,' ' Orm of Abernithi,' ' Laurence the son of Ilorm,' * Laurence of Abernethi,' * Patrick de Abernethyn.' ' Patrick the son of Laurence,' that the lay abbots of Abernethy meet us in record. Their monastic character and style appear only when it is necessary that the King or the Bishop should distinguish the peculiar tenure of their inheritance.
