Joan ___ (living 6 Aug 1320; gift of property in Asthall and surrounding for priest to sing for souls of self, deceased husband, and children, recorded 10 Oct 1321) [CPR 1317:495; LRS 90:78; see also CPR 1313:475]

From Richard de Cornwall circa 1255 - 1296

Richard was probably born sometime around the mid 1250s (1), the illegitimate son of Richard, earl of Cornwall (5). His mother is unknown, although it has often been claimed, without any proof, that she was named Joan de Valletort.

He was made Sir Richard by 1277, at which time he was a knight serving for his brother Edmund, earl of Cornwall (4). He maintained a close relationship with Edmund throughout his life, often witnessing Edmund's grants, travelling overseas with him, and fighting alongside him.

He married a woman named Joan (7)(10)(11), and their eldest known son Edmund (7)(18) was born around the late 1270s (8). They had another son Geoffrey about 1288 (12)(19). They may also have had another son Richard and a daughter Joan, amongst others (13).

In 1280 he went overseas with Edmund his brother, presumably on state business (14). In 1286 he had his seal stolen (15). In 1290 he witnessed a grant by his brother Edmund, giving land to Hailes Abbey, which his father had founded (16).

He died in the Siege of Berwick in 1296 (17). His wife survived him by at least 24 years (11)


  • 7. "Calendar of Inquisitions Post Mortem and other analogous documents preserved in the Public Record Office, Vol III, Edward I", 1912, entry no. 604, concerns the extensive lands of Edmund, Earl of Cornwall. Most of it is of no relevance here, but the following snippets are : Writ 26 Sept 28 Edw I (See Calendar of Fine Rolls, Edw I, p433) Edward, king of England his kinsman, is his next heir and of full age. Writ to William Haward and Thomas son of Eustace, concerning the manor and advowson of Thunnock whereof the said Margaret seeks 1/3 against Edmund son of Richard de Cornubia, and 1/3 of 1/3 against Joan late the wife of the said Richard &c. 23 Oct, 31 EdwI by council.

"Calendar of Inquisitions Post Mortem and other analogous documents preserved in the Public Record Office, Vol VIII, Edward III", entry no. 461, states: RICHARD SON OF GEOFFREY DE CORNUBIA Writ 24 October, 17 Edward III. NORTHAMPTON, Inq taken at Daventre, 30 October, 17 Edward III. ....       Norton. The other moiety of the manor (extent given), held, by the grant of Joan, late the wife of Richard de Cornubia, to the said Richard and the heirs of his body, of the said Joan and her heirs by the service of a rose yearly, by virtue of a fine levied in the king's court at Westminster in 10 Edward II.

  • 13. A number of claims have been made for other children of Richard, but with only assertion and/or speculation to back them up. The most commonly asserted one (or two!) is of a daughter Joan, and this is based upon her being the sister of a Richard de Cornwall, rector of Walsoken (as per the IPM of her husband Sir John Howard, which names her as this Richard's sister). Hence the claim for both of these depend solely on Richard the rector being son of this Richard. Whilst this is feasible, and indeed it would seem likely that this Richard, whose father shared his name, should also name a son Richard, I have been unable to find any evidence to connect the two. Richard the rector, was first mentioned in the Patent Rolls of 1292 as being the king's clerk. Assuming him to be "of age" at the time, he would have to have been born no later than 1271, and hence the eldest son. Considering that he was still alive at the time of Edmund, earl of Cornwall's, IPM in 1300 (indeed he appears to have lived until at least 1331), it seems telling that he is not mentioned therein, along with his purported brothers, as holding land which the earl gave to their father. It seems to me that he is more likely to have been the son of this Richard's brother, Walter, and is not mentioned the said IPM, because Walter was still alive, and so still in possession of any land that was under dispute, rather than any of his children.


From Sir Richard of Cornwall (d.1296) was an illegitimate son of Richard, 1st Earl of Cornwall (1209-1272) (the second son of King John (1199-1216)) by his mistress Joan de Valletort.

He married Joan FitzAlan, daughter of John FitzAlan, 6th Earl of Arundel, and by her had three sons and a daughter, including:

Joan of Cornwall, wife of Sir John Howard, from whom the Howard family, Dukes of Norfolk, are descended.[13]


Heraldic escutcheon from mural monument in Branscombe Church, Devon, to Joan Tregarthin (died 1583). The arms are Wadham (9 quarters), impaling Tregarthin (6 quarters). The 4th quarter of the latter is:A lion rampant in chief a label of three points a bordure engrailed bezantee

He adopted the arms of his father with difference a bordure engrailed. These arms were later used by the following families which claimed descent from him:

Cornewall Baronets, which family claimed descent from a younger branch of the de Cornewall family, Barons of Burford, lineally descended from Sir Richard of Cornwall (d.1296).[14]

Tregarthin family of Cornwall, with addition of a label. The arms on the monument in Branscombe Church in Devon to Joan Tregarthin (died 1583), wife of John Wadham (died 1578), quarter de Cornwall. The ancestry of Joan Tregarthin, was set out by Davies in his "Parochial History of Cornwall", concerning the parish of Goran, as follows:[15]

"At Tregarden lived John de Tregarthyn, temp Edward I, how long before I know not, after which his posterity in this place married with the great inheritrixes of Pever, Chamberlayne and Hendower, of Court, in Branell, by which last, by the Cornwalls of that place, they were lineally descended from Richard, Earl of Cornwall, King of the Romans, by his concubine Joan de Valletort, widow of Sir Alexander Oakeston".
