Notes:

NOTE: According to the website FamilySearch.org Sir Ralph married Margaret Michell around 1519. Then it mentions that he married an Elene Or Ellen Mitchel in about 1533. This could possibly be a name change of Margaret to Ellen around the time that Margaret's first husband Matthew Barre (believed to be dead) turned up in London and almost caused some problems for the Sadleirs. This is unconfirmed however and I welcome any information regarding this case. There is a Parliamentary Act from 1545 at Her Majesty's Stationery Office in Norwich which legitimized Sir Ralph's children.
