From the Online Medieval Source Bibliography [x]: This scroll, nearly 20 feet long, was produced in honor of Edward IV’s coronation in 1461. The king’s scroll shows Edward’s genealogy and, far from being a mere commemorative document, served as propaganda demonstrating the legitimacy of the first Yorkist king, who had gained the thrown by defeating his predecessor, Henry VI in battle.

The Bodleian has a lot of great stuff too, which you can find here: [Link] The earliest looks like it is from the end of the 13th century.
Highlights from the Bodleian:
MS. Bodl. Rolls 5, view 36: Genealogy of the Kings of England to Richard III. Chronicle of the Percy Family to 1485. c. 1485 [Link] – hopefully this will work. Linking to specific items in the Bodleian is always… interesting. There are a lot of pages from this one. Totally cool.
