Joan Tudor

There is no contemporary, or close to contemporary, evidence for the existence of Joan Tudor, who seems to have been invented as a way to give the Cromwells a Tudor heritage. (That Jasper Tudor did have an illegitimate daughter, Helen or Elen, is attested to early on, however.)

Bartrum gives "Margred verch Thomas" as the wife of William ab Ieuan, and the mother of his children. Joan Tudor is not mentioned. The Wikipedia article for Jasper Tudor discusses Joan Tudor in detail, but does not give any reference for her. (See https://en.wikipedia.org/wiki/Jasper_Tudor,_Duke_of_Bedford#cite_no...) Nor does John Burke's Genealogical and Heraldic History mention her.
