Idonea de Clifford is a descendant of Magna Carta surety barons Roger le Bigod, Hugh le Bigod, Richard de Clare, Gilbert de Clare, John de Lacy and Saher de Quincy.



Idoine was grandmother to both of the two great northern rivals and Shakespearean characters, Westmorland and Northumberland (father of Hotspur).


Douglas Richardson writes:[1]

The correct name of Henry de Percy's wife is Idoine de Clifford. "Idonia" or "Idonea" are the Latin forms of her name and should be avoided.
There are no less than five separate visitations/medieval sources which name Idoine, wife of Sir Henry de Percy, as a Clifford, or the daughter of Lord Clifford:
1. Archaeologia Aeliana 3 (1844): 40 (Chronicles of Alnwick Abbey: "Iste Henricus disponsavit idoneam filiam Domini de Clyfford et genuit ex ea Anno Domini 1320 Henricum quartum et tertium Dominum de Alnewyk et alios plures filios et filias inter quos erat Thomas qui postea fuit Episcopus Norwicens ...").
2. Atkinson, Cartularium Abbathiæ de Whiteby 2 (Surtees Soc. 72) (1881): 690-696 (Percy ped.: "The fourth Henry Lord Percy ... gat on Idonea Clyfford Henry, William, Richard, Maude, Alianour Fitzwater, Roger, and Margarett that was maried to the Erle of Angus Sonne and his heire.").
3. Flower, Vis. of Yorkshire 1563-4 (H.S.P. 16) (1881): 241-244 (Percy ped.: "Henry 4 Lord Percy. = Ida doughter of the Lord Clyfford.").
This item is available online at the following weblink:
4. Harvey et al., Vis. of the North 3 (Surtees Soc. 144) (1930): 18-20 (Percy ped.: "Henricus Percy = Idonea Clifforde").
This item is available online at the following weblink:
5. Harvey et al., Vis. of the North 4 (Surtees Soc. 146) (1932): 17-24 (Lassels ped.: "Idonæ [Clifford] mar: to Henry lord Percy").
This item is available online at the following weblink:


Given that we know that Sir Henry Percy was born in 1300 or 1301, and given that Henry's son and heir, also named Henry, was born about 1322-5, the birth of Idoine de Clifford would necessarily have to fall about 1300-1310. Given the chronology, Idoine de Clifford can be placed as a daughter of Robert de Clifford (died 1314), 1st Lord Clifford, and his wife, Maud de Clare, which Robert and Maud were married in 1295. Idoine de Clifford was surely named for her father's maternal aunt, Idoine de Vipont (died 1333), wife of Roger de Leybourne, Knt., and John de Cromwell, Knt., Lord Cromwell.


Idoine de Clifford was the daughter of Sir Robert de Clifford of Appleby, 1st Baron Clifford, and his wife Maud de Clare, daughter of Sir Thomas de Clare of Thomond.


She married[2] Sir Henry Percy, 2nd Lord Percy, son of Sir Henry Percy and his wife Eleanor, daughter of Richard Fitz Alan (or de Arundel), Knt., 8th Earl of Arundel.[3]

Henry de Percy was born at Leconfield, Yorkshire, either 2 Feb 1299/1300 (father's inquisition) or 6 Feb 1300/1 (proof of age.) [4][4]

Public Life

Sir Henry was "knighted by the King at York in 1323."[3]


Sir Henry de Percy, 2nd Lord Percy, died at Warkworth, Northumberland 26 Feb 1351/2, and was buried at Alnwick Abbey, Northumberland. He left a will dated 13 Sept 1349, proved 12 March 1351/2, in which he bequeathed his son Henry, a vessel of salt with the arms of Percy and Arundel. His widow, idoine, died 24 August 1365, and was buried at Beverley Minster, East Riding, Yorkshire. [4]


Documented Issue

Idoine and Henry had 5 sons and 4 daughters:[5]

Disputed Issue

Douglas Richardson's books, most recently Royal Ancestry, published in 2013 [4], do not list a son Richard. However, in material attributed to a post by Richardson (included in this profile), Richard is listed. Therefore Richard is retained here as a disputed son.

Liz, I see a merge was just completed, but no one cleaned up the profile. I'll delete the stuff from the merged profile. Thanks.

update: looks like it was reviewed & badged! (and sorry, but it seems the suggested line link I posted went away - try the backup copy) ~ Liz, Sept. 28, 2015

Hi! This profile is in the Magna Carta trail between the Gateway Ancestor Robert Peyton and Magna Carta surety baron Saher de Quincy.

See Magna Carta suggested lines for the profiles between Robert and Maud, de Quincy's 3x-gr-granddaughter. This trail has just been placed in the queue for review. For more information about the Magna Carta project, see the project page. To see information about the 800th Anniversary of the signing of the Magna Carta, see Magna Carta 800th.

Cheers, Liz

update: all done - this profile's ready for review when the rest of the trail is done

Hi! I'm working on a Magna Carta trail for Major Robert Peyton, a Gateway Ancestor, to Ralph Neville, a descendant of a Magna Carta surety baron. I noticed that this profile for his grandmother is pretty much done & ready for review by the project, if it were part of a trail, so I plan to extend the trail for Robert Peyton through Ralph's mother Maud Percy and this profile. Message me if you have any questions. Thanks, Liz
