Katherine Stafford Countess Suffolk: Around 1376 she was born to Hugh Stafford 2nd Earl Stafford and Philippa Beauchamp Countess Stafford.

She the daughter of Hugh Stafford 2nd Earl Stafford and Philippa Beauchamp Countess Stafford. He the son of Michael de la Pole 1st Earl Suffolk and Katherine Wingfield Countess Suffolk.

Philippa Roet: Around 1346 she was born to Giles "Payne" Roet. Before 1367 Geoffrey Chaucer and she were married at St Mary de Castro Leicester, Leicestershire. Excerpta Historica Page 152. Philippa, his eldest daughter, is stated to have been the maid of honour to Philippa Queen of Edward the Third who by the name of "Philippa Pycard" obtained a grant of one hundred shillings per annum on the 20th January 1370, and married Geoffrey Chaucer, to whom, in consequence, it is supposed, of this connexion, the Duke of Lancaster granted the Castle of Dodington. Of John of Gaunt's connexion with Chaucer, however, no proof has been found; and the circumstance of the lady assigned to him for his wife being styled "Philippa Pycard," instead of Roelt, renders the assertion, that she was the sister of the Duchess of Lancaster, extremely doubtful. Around 1387 Philippa Roet died.
Evelyn's Diary. 09 Jun 1654. Dined at Marlborough [Map], which having been lately fired, was now new built. At one end of this town, we saw my Lord Seymour's (age 64) house, but nothing observable save the Mount, to which we ascended by windings for near half a mile. It seems to have been cast up by hand. We passed by Colonel Popham's (age 49), a noble seat, park, and river. Thence, to Newbury [Map], a considerable town, and Donnington, famous for its battle, siege, and castle, this last had been in the possession of old Geoffrey Chaucer. Then to Aldermaston, a house of Sir Humphrey Forster's, built à la moderne. Also, that exceedingly beautiful seat of my Lord Pembroke (age 33), on the ascent of hill, flanked with wood, and regarding the river, and so, at night, to Cadenham, the mansion of Edward Hungerford (age 21), Esq, uncle to my wife (age 19), where we made some stay. The rest of the week we did nothing but feast and make good cheer, to welcome my wife (age 19).
Pepy's Diary. 14 Jun 1663. By and by in comes Sir J. Minnes (age 64) and Sir W. Batten (age 62), and so we sat talking. Among other things, Sir J. Minnes (age 64) brought many fine expressions of Chaucer, which he doats on mightily, and without doubt he is a very fine poet1. Sir W. Pen (age 42) continues lame of the gout, that he cannot rise from his chair. So after staying an hour with him, we went home and to supper, and so to prayers and bed.
Note 1. Pepys continued through life an admirer of Chaucer, and we have the authority of Dryden (age 31) himself for saying that we owe his character of the Good Parson to Pepys's recommendation.
Evelyn's Diary. 03 Aug 1667. Went to Mr. Cowley's (deceased) funeral, whose corpse lay at Wallingford House, and was thence conveyed to Westminster Abbey [Map] in a hearse with six horses and all funeral decency, near a hundred coaches of noblemen and persons of quality following; among these, all the wits of the town, divers bishops and clergymen. He was interred next Geoffry Chaucer, and near Spenser. A goodly. Monument is since erected to his memory.
[his daughter] Elizabeth Chaucer was born to Geoffrey Chaucer and Philippa Roet.
