Robert Wylkynson
Robert Wylkynson (sometimes Wilkinson) (ca. 1450 – Eton after 1515) was one of the composers of the Eton Choirbook. Wylkynson became parish clerk of Eton in 1496, then in 1500 he was promoted to Informator - the master of the choristers.

Only four works survive: 
 2x Salve Regina
 Jesus autem transiens/Credo in Deum à 13
 motet O virgo prudentissima (fragmentary)

But these works show Wylkynson to have been "an extremely ambitious composer and a more than competent one."
