Note: I suggest that this "3rd son" of Roger and Gwladus was not a child or grandchild of Gwladus, but was raised by her with his uncles after his father and her husband died in 1415 at the Battle of Agincourt. A son born to Gwladus in 1410 could not have been the "recently married son, Roger" mentioned in Roger of Bredwardine's Wikipedia biography. But a son born of a previous marriage could have been: see this profile of Roger Ieuange, suggested son of Roger of Bredwardine and an unknown mother, who died in 1415 and left a son, Roger of Tretower, who was raised by Gwladus.


Sir Roger Vaughan of Tretower, married Denys, daughter of Thomas ap Philip Vychan Vaughan, 2ndly Margaret daughter of lord Audley and widow to lord Powys.[1]

Sir Roger Vaughan of Tretower, mentioned in page 3 of this pedigree, besides the children there named had several illegitimate sons and daughters; some of them are noticed as ancestors of several branches of this family;

  1. his youngest illegitimate son by an illegitimate daughter of a prior of the monastery of Abergavenny, called Prior coch or, the red haired prior, was named Thomas Vaughan, he was knighted and a great favourite of Richard the third by whose command however he was afterwards beheaded at Pomfret; he married and had issue
    1. a daughter, married to Sir John Wogan of Wiston,
    2. and a son, Harry Vaughan,
      1. whose son Sir Tho Parry, was comptroller of the household and master of the wards to queen Elizabeth, he married Anne, daughter of Sir William Reed of Borestall in Bucks, by whom he had issue
        1. Sir Thomas Parry, chancellor of the exchequer and privy counsellor in 1607; whose wife was Dorothy Brooks one the maids of honour to queen Elizabeth.[2]

Sir Roger and Eva Coch never married.

Rev. Daniel - problem solved if the father of this Roger was not the "hero of Agincourt" Roger who married Gwladys ferch Dafydd Gam. Take a look at a speculative profile for such a person: Roger (1394-1415).

just an observance,

I doubt seriously, that a 14 y.o. was one of the (apparently few) Brecons that bested the 16 French Knights ... I suppose its possible, but doesn't seem right.

from a post on my page in response to the question about dates:

re: comment on Denys marriage -dates are guesstimates - source for marriage is History of Breckinshire, pp. 506/7

Welsh boys were considered men at 14 and would go to battle at that age, so he could have been born as late as 1400. While they may have gone to battle at 14, I don't know when they might have married, and the Wikipedia article also says he was "recently married"... to whom? This profile says he married his first wife Denys in 1431 & the battle of Agincourt was 1415.

Any idea of the source for the 1431 marriage - or the 1410 birth?

The Wikipedia article suggests it was Roger of Tretower, son of Roger & Gwladys, who was the younger Roger Vaughan at Agincourt, but his profile says b. 1410. He would need to have been born closer to 1395-97, which is poss. based on shown parent's b. dates of 1377 & 80.
