After your first message I put this on the talk page but you maybe didn t have time to read it before the article was deleted If you want detail about why it is historically nonsense York and Lancaster were branches of the house of Plantagenet competing with each other but not with some independent Plantagenet faction The house of Tudor was descended maternally from a branch of the Lancasters who did not survive the wars The first Tudor King Henry VII came to the throne by winning the Battle of Bosworth in 1485 which was Tudor vs York The next year he married Elizabeth of York which helped legitimise his claim to the throne but any tensions in the next few years were Tudor vs York not Tudor and York vs Plantagenet assemblies Research I read the articles Plantagenet Tudor dynasty Battle of Bosworth Henry VII of England Elizabeth of York checked the links and a few on line sources about Norton Canes and off line checked A R Myers England in the Late Middle Ages p 185 which lists risings and disturbances from 1486 to 1497 but does not mention this and C Ransome A Short History of England p 173 ditto
