Everything we know about the children born to Edmund of Lancaster and Aveline de Forz comes from the Anglo-Norman chronicles written for Edmund's niece Mary (1279-1332), daughter of King Edward I, by the Dominican friar Nicholas Trevet. This chronicle is packed with a good deal of intimate Plantagenet family lore that Mary probably told Trevet, and given that his source was a ranking member of the family, his information is not to be rejected out of hand. (Surprisingly though, the chronicle has never been fully edited.)
According to Trevet, Aveline was the mother of two children who did not survive. We know that her marriage to Edmund was consummated in Feb 1273, the month in which Aveline turned 14, and that she died in November 1274. There is not really enough time there to allow for pregnancies, which argues that the children were twins. Furthermore, it is probable that the twins did not survive birth. According to the laws and customs of England, if a man married an heiress and she bore him a child that lived long enough for its cries to be heard within the birth chamber, the husband and father was entitled to continue to hold his wife's inheritance for the rest of his life, whether the child survived or not. (This was known as "the courtesy of England.") We know that Edmund of Lancaster did not hold Aveline's lands after her death; thus any children she bore him could not have survived birth. In the thirteenth century it was rare for twins to survive at all (Blanche of Castile's twin sons barely survived birth), and a dangerous twin delivery could easily explain Aveline's early death when she was not yet 16.
Aveline was the heiress to both her parents--to her father for the earldom of Albemarle and the barony of Cockermouth, and to her mother (or rather grandmother) for the earldom of Devon and the lordship of the Isle of Wight. [Ref: John Carmi Parsons SGM 12/3/1998]
