This is possibly the most ridiculous piece of nonsense that has ever been written in English history! Actually - and this is true - I have a second cousin who is 5 feet tall. While she is small for a woman her parents are both tall - her father is over six feet tall and her mother 5 feet six. Does this mean that she is not their daughter? Of course it doesn't! Her mother's mother was also very small for a woman! (doh!) It's simple genetics! 
 The idea that because Edward was much taller than his father that must mean he is illegitimate is utter b*ll*cks! Furthermore, no-one has ever seen a picture of Edward's father or mother as none exist, so no-one can possibly make any value judgment in regard to that!  
 I saw that piece of nonsense on the telly about this. The idea that the Duke of York's wife would risk everything (including her own life) by having an affair with a nobody beggars belief. This nobody in question would certainly have had to have had balls to do the deed that's for sure, because if it were true, (which I'm quite sure it is not)then they are the first things that he would have lost when Richard found out!  
 Do people really think that the Duke of York would have been so stupid as to have not realised that his wife had been unfaithful if she had been? If he had really not seen her for several months as that TV nonsense suggested then I think he would have known! (Presumably this prat thinks he tied a knot in it for a few months like all virile young men do - of course he wouldn't have seen his wife (oh no of course not!) no way she could have possibly visited him on campaign (on no of course not!)  History does not portray Richard as an idiot! Nor does it portray him as tolerant of weakness. He would not, I am quite certain have raised his wife's bastard as his own and called him his heir!
