Birthdate of 1360 after son Thomas (about 1350)???

Question

The birthdate for John Bedlisgate (1360) is after his son, Sir Thomas Bedlisgate's (about 1350).  John's wife Mary Beauchamp is also before (1365).  Can this be cleared up?

Comments

It could be dismantled.  It's the combined remains of more than one failed attempt to improve the ancestry of Elizabeth Woodville.  Too painful to figure out what might be salvageable.

Looks like even the name Bedlisgate is incorrect, the family seem to be named Bittelsgate (Bytelsgate, Bytelysgate)

Answer 1

Looks like this John Bedlisgate's birthdate was changed from 1360 to 1315 without any thought about the birthdate of his parents which are currently listed just 4-5 years before their son.  Also the surname changes going back before the father to St John so not sure how accurate that is.  Probably needs in depth research and explanations created.
