  Here is another - this is from the FA article on the film of Richard III. I removed some actor trivia but kept the rest intact:  The House of York  *King Edward IV of England, the newly-crowned King of England, who, with the aid of his brother, Richard, has secured his position by wresting it from Henry VI of the House of Lancaster.  *George, Duke of Clarence, brother of the new King.  *Richard, Duke of Gloucester, later King Richard III), the malformed brother of the King, who is jealous of his brother's new power, and plans to take it for himself.  *Prince of Wales (later, for a brief while, King Edward V), the eldest son of the King, who holds many strong beliefs, and wishes one day to become a Warrior King.  *Duke of York, the younger son of the King.  *Duchess of York, the mother of the King.  *Jane Shore, the King's mistress.  *Duke of Buckingham, a corrupt official, who sees potential in Richard's plans and becomes a fellow conspirator until Richard swindles him.  *The Lord Hastings (Lord Chamberlain), a companion and friend of Richard who is accused of conspiracy by Richard and is abruptly executed.  *The Lord Stanley. Stanley has a certain dislike for Richard and is not totally willing in his cooperation with him. Stanley eventually betrays Richard at Bosworth and engages him in a one-on-one duel.  The House of Lancaster  *Queen Elizabeth, Queen Consort of Edward.  *The Lord Rivers, brother of the Queen Consort. *The Lord Grey, brother of the Queen Consort.  *The Lord Dorset, eldest son of the Queen Consort and stepson of the King.  * The Lady Anne, a widow and an orphan thanks to the acts of Richard, though she cannot resist his charms and eventually becomes his wife.  * Henry, Earl of Richmond (later Henry VII, first of the House of Tudor). Henry, Richard's enemy, claims his right to the throne, and meets him at Bosworth.  Again - very helpful in following the synopsis and keeping track of who is with each faction.
