Well I made a mistake on that, but it would only make sense that Henry VIII murder his son (Henry Fritroy) if he had a legitimate heir according to the book on Fritzroy. Anyway, it seems like Henry wasn't too concerned about Fritroy's death, judging from his simple and rushed arrangement on his furneral. Especially since he was an Earl and natural son of the king.
Sorry, what tosh :-)
Henry Fitzroy was publicly exalted aged 6 at St Georges Chapel, Windsor. Installed as Knight of the Garter then formally created Duke of Richmond and also Somerset and the Earldom of Nottingham (all titles of Royal Association)
Letters Patent gave Richmond precedence over all dukes already created or to be created in the future (except legitimate issue of the King's body.) Large estates were settled on him and he was also made Lord High Admiral, Lieutenant-General North of Trent and Warden of All the Marches toward Scotland.
Henry entrusted funeral arrangements to Fitzroy's Father-in-Law (the Duke of Norfolk). The King gave orders that the corpse be wrapped in lead and was furious when he heard that the corpse was carried in a wagon, covered with straw and with only 2 attendants as mourners.
