General Notes

Sir Roger Bertram, of Mitford, Northumberland, son and heir of Roger Bertram (a1) of the same, by Agnes, his wife (b), was born 5 December 1224. He succeeded his father in 1242, and having proved his age, he did homage and had livery of his inheritance, 28 June 1246. He had a grant of free warren in his demesne lands in Mitford, Felton, etc., 13 September 1257, but in November following, for a reason not stated, the escheator was ordered to take his lands into the Kings hand. He was sum. ciem equis et armis from 17 Jan. 1257/8) to 6 March 1263, by writs directed Rogero Bertram de Mitord. He sided with the Barons against the King, and was taken prisoner at Northampton, 3 April 1264,) but was released soon after, and fought at Lewes 14 May. He was summoned to Parliament 24 December 1264, by writ directed Rogero Bertram, which writ, however, having issued in rebellion, should not create a Peerage dignity. He alienated nearly all his extensive possessions.

He married Ida. He was living 6 March 1271/2 and died s.p.. legit. (a2), aged about 48. His widow married, before 14 April 1273 as 2nd wife, Sir Robert DE NEVILL, of Raby, co.

She married, 3rdly, without licence, before 8 May 1285, as 2nd wife, Sir John FITZ MARMADUKE, of Horden and Ravensholm, co. Durham, who died shortly before 16 August 1311. She was living 18 May 1315.

He left an only child, Agnes, who was seized of Mitford and Felton, which she give to Alianore, the Queen Mother.

--------------------------------------

Roger Bertram, in the 42nd of Henry III [1258], had command with other great barons of the north to march into Scotland for the rescue of the young King of Scots, the King of England's son-in-law, out of the hands of his rebellious subjects; but, in the 48th of the same monarch [1264], being in arms with the other rebellious barons, he was taken prisoner at Northampton, and his castle of Mitford seized upon by the escheator of the crown* while he was himself committed to the custody of William de Valence. He must, however, have made his peace very soon afterwards, for we find him summoned to parliament as a Baron (the first by writ) in the next year, 14 December, 1264. His lordship had issue by Joan, his wife (who m. 2ndly, Robert de Neville),

Roger, his successor.
Agnes, m. to Thomas Fitz-William, Lord of Elmeley and Sprotborough, co. York, and had issue,
William Fitz-William, who was succeeded by his son, William FitzWilliam...
Isabel, m. to Philip Darcy, and had Norman Darcy, who was s. by his son, Philip Darcy...
Christian, m. to Penulbury, and had a son, Elias de Penulbury...
Ada, m. to --- de Vere, and had a dau., Isabel, whose son, Gilbert de Aton...

The baron was s. at his decease by his son, Roger Bertram, 2nd baron...

* The precedence of the escheator was next to the judge.

Note: In terms of Roger's issue, Burke seems to be confusing Roger with his father, also Roger, who m. Agnes.  This Roger only had one legitimate issue, Agnes, & she died without issue.  I have indications that Roger had a daughter, probably illegitimate, who m. Hugh de Eure, so I am making her the daughter by Joan mentioned by Burke above.  I believe that his wife Ida was born much later than Roger, leaving a lot of time prior to the marriage for Roger to sire illegitimate children.

Note also: Magna Charta Sureties, line 118-2, has Christian Bertram, wife of Robert de Ros, as daughter of Roger & Ida.  This is obviously a mistake - as Christian is daughter of Roger & Agnes.
