• Notes

  Margaret, de jure suo jure (according to modern doctrine) BARONESS BEAUCHAMP OF BLETSOE, widow of John (BEAUFORT), 1st DUKE OF SOMERSET (who died s.p.m. 27 May 1444), and before that of Sir Oliver ST. JOHN, sister and heir of John BEAUCHAMP, daughter of John BEAUCHAMP, of Bletsoe (according to modern doctrine 4th and 3rd LORDS BEAUCHAMP OF BLETOE), by Edith, daughter of Sir John STOURTON. His [Lionel de Welles'] widow died, apparently shortly before 3 June 1482, certainly on or before 20 July following. [Complete Peerage XII/2:443-4, (transcribed by Dave Utzinger)] --------------------------------------- Margaret, daughter of the John Beauchamp, of Bletso, by Edith, daughter of Sir John Stourton, and widow of Sir Oliver St John. [Burke's Peerage] -------------------------------------- Margaret de Beauchamp (probably by (1) Margaret Holand, but not certain), b. c 1412, d. 1482; m. (1) Sir Oliver de St John, d. 1437, of Penmark, co. Gloucester; m. (2) John Beaufort, Duke of Somerset. [Magna Charta Sureties] -------------------------------------- Note: CP & Burke's have Margaret as daughter of 2nd wife, Edith Stourton; while MCS and AR have her (probably, but not certain) as daughter of 1st wife. Margaret's birth date of c 1412 is the same as her father's death date, yet he married a 2nd wife after Margaret Holand; if Margaret was daughter of Margaret Holand, it doesn't give Sir John much time to get married again and then die. I am going with the 2nd wife.
