Notes:

Her father was Payne Roet. She is well known by her first married name as Katherine Swynford. She was probably born in Picardy, France. She was the governess to Duke John of Gaunt's daughter by his first wife. Around the time Katherine's first husband died, she became the mistress of John of Gaunt and had 4 children by him. When John's second wife died, he married Katherine and had all of their children pronounced legitimate. She became Duchess of Lancaster in 1396 or 1397 with the later being the more favored date. There is a current novel out about her that is very popular by Anya Seton called "Katherine".
