According to the Armitage Robinson (Robertson?) biography of John of Gaunt,
Blanche was not Katherine's daughter by Swynford, but Gaunt's OOW child by one
of Queen Philippa's damsels. The mother's name is known but escapes my memory
at the moment; possibly Marie de St-Hilaire, but that might also have been HER
mother's name (both her parents are known).
The date usually given for John Beaufort's birth is ca 1372. If Katherine's
first husband died late in 1371, John could still have been conceived in said
husband's lifetime. But in fact we don't know exact dates or even years of
birth for any of the four children Katherine and Gaunt produced.
