Whilst the precise date of the foundation is not clear, in his history of the school "Ruthin School: The First Seven Centuries", Keith Kenyon-Thompson suggested that 1284 was the most likely date and Reginald de Grey the most likely founder. In any event it is clear from the Taxatio of 1291 that there was a flourishing collegiate church and school at Ruthin.
