49. Joan GREYSTOKE, supposedly died before age 20. If so, born say 1402, died 1422.
50. William FITZHUGH, the 4th Baron Fitzhugh, born about 1399, died 22 October 1452. He married before 18 November 1406. How do you say this is possible? We've crossed back into the time where parents arranged their children's marriages and children were, in fact, often married to each other for property and dynastic reasons. William was aged 26 in the year 1425. See: Complete Peerage under Dacre, Fitzhugh, Willoughy, and Scrope. This couple is also ancestral to Ellen (Newton) Carleton of Mass. for whom see NEHGR 111:195-200, specifically at 198.
51. Margery WILLOUGHBY, sister of Sir Thomas Willoughby, no. 40 above. She was born ca. 1400 and predeceased her husband.
52. Christopher CONYERS, born about 1400 and died in 1460. Flowers, Visitation of Yorkshire, p. 74 (Conyers).
53. Helena ROLLESTON. Born say 1400, She died 6 August 1444.
54. John WYCLIFFE, born say 1390 and living in 1444. See The Yorkshire Archaeological Journal, vol. 19, pp. 415-16; The history and antiquities of the seignory of Holderness, by Poulson (1841), II: p. 239; and Dugdale's Visitation of Yorkshire, p. 353. His son Richard married the daughter of Christopher Conyers, no. 52, above.
55. Ann/Agnes ROKEBY.
56. Thomas CLIFFORD, the 8th Lord Clifford, born 25 March 1414, died at the 1st Battle of St. Albans on 22 May 1455 [he was a Lancastrian fighting for King Henry VI]. He married after March 1424. He contracted a second marriage in May 1453, but it didn't take place. Flowers, Visitation of Yorkshire (Dacre), pp. 83-85. Complete Peerage under Clifford and Dacre.
57. Joan DACRE, born say 1415, died before 1453.
58. Sir Henry BROMFLETE, Lord Vessy/Vescy, born say 1390, died at London on 16 January 1468/69. He married first between 29 September 1415 and 27 April 1416, Joan HOLLAND, Duchess of York, widow sucessively of Edmund of Langley, Duke of York; William WILLOUGHBY, 5th Lord Willoughby (no. 80, below); and Henry le SCROPE, 3rd Lord Scrope. They had no children and she died on 12 April 1434. He married say 1435-6 secondly below. Among many visitation and other primary sources see: Cockayne's Peerage, Vol. VIII, p. 32.
59. Eleanor FITZHUGH, sister of William Fitzhugh, no. 50 above. She was born say 1400 and died at Newington, Middlesex on 30 September 1457. She, herself, was the widow successively of Philip Darcy, 6th Lord Darcy and Sir Thomas Tunstall who died sometime after May 1431.
61. Margaret BEAUCHAMP, born about 1410, died shortly before 3 June 1482. After her marriage to Oliver St. John she married John BEAUFORT, the Duke of Somerset, and then Lionel de WELLES, the 6th Lord Wells, no. 42, above. By her second husband she was the maternal grandmother of King Henry VII of England. Thus, her other grandchildren, including Anne St. John, no. 15 above, and her husband Henry Clifford were half 1st cousins of the King and enjoyed his protection and favor.
62. Sir Thomas BRADSHAIGH, born say 1400. This is my own formulation. Most compiled royal ancestries give the wife of Sir John St. John as Alice Bradshagh or Bradshaw, daughter of Sir Thomas Bradshagh of Haigh, Lancashire. This man is said to have married a daughter of Sir William Sherburne of Stonyhurst. Arms of Bradshaigh here.
63. Alice SHERBURNE, born say 1400. According to this work, there is no William Sherburne that could be her father. However, the Sherburne family is ancestral to Peter Worden of early New England, another of my ancestors. Using the work of Douglas Hickling on the Sherburne and Tempest families, I do believe that I have found her parents.
In this group we have another eight couples, three of whom (Conyers, Wycliffe, and Bradshaigh) do not appear in standard compiled works for royal genealogy. We also see the start of the ancestor collapse for Anne Eure (that is in generation number seven, there will be 64 slots occupied by only 60 individuals. That's not much, but the collapse accelerates rapidly in successive generations).
