• General Notes

  Sir Edmund de Arundel, knt (b ca 1327; d 1376-1382), bastardized by the annulment. Edmund was nevertheless knighted, married at the age of twenty, in the summer of 1347 [2] Sybil de Montacute, a younger daughter of William Montacute, 1st Earl of Salisbury and Catherine Grandison, whose elder sister Elizabeth was married to his maternal uncle (the uncle may have arranged this marriage). Edmund protested his bastardization bitterly in 1347, but was apparently ignored. After his father's death in 1376, Edmund disputed his half-brother Richard's inheritance of the earldom and associated lands and titles in 1376 and apparently tried to claim the six manors allotted to his deceased mother. He was imprisoned in the Tower of London in 1377, and finally freed through the intervention of two of his brothers-in-law (his wife's brother John de Montacute and the second husband of Elizabeth de Montacute, Lady Le Despencer).[3] They had three daughters who were his co-heiresses and who brought a failed suit in 1382 against their half-uncle the Earl:
  Elizabeth de Arundel, who married Sir Leonard Carew and has descendants

"Philippa became a widow, September 30, 1393, and died September 13, 1399." (I.P.M., 17 Ric. II., 53; 21 Ric. II., 50; 1 H. IV., 14, 23, 24.)[5]
