Master John de Sancto Claro is indexed in the Calendar of Papal Registers as clerk of the diocese of Canterbury, 1291 (10 Kal. Mar.), as rector of Fulcham, or Folcham, therein (4 Non Mar. same), and presently thereafter as Canon of London, and the hostility towards him by the Archbishop of Canterbury was silenced by Papal Mandate. Nicholas III issued a dispensation on account of the illegitimacy of the said John de St.Clair.
"St.John's Hospitalle (Northampton) was originally founded by one William Sancte Clere, archdeacon of Northampton, and brother to one of the Simon Saintcleres, as sum of St.John's name them; but as I have redd alway they were caulid Saincteliz (Sylvanect ensis) and not S.Clere": Thus Leland. The similarity in sound may well explain his doubt. The St.Liz family held the Earldoms of Huntingdon and Northampton. There is a charter of date 19 Henry III, "Simon de Seyntclere et Anna Uxor ejus; Seyton boscus quiet' de vasto et regard' forestae, etc.; Rotel", which tends to show that these St.Cleeres and St.Liz were all of one stock. The name also assimilates with St.Hilary. An Aelard de Seynteler was son of James de St.Hillary, and his (Aelard's) sister Maud became Countess of Clare and Hertford. In a carta of William of Albini (about 1127) appears the name of Aelardus de Saincler, who promises to furnish for his lands two knights' fees in case of war, but the "c" gets faint through interchange with Seynt Liz, the alternate name, and is lost gradually. Seynteler grew to be Seynt Eler or Seynt Elerio, and by aspiration ended in the "St.Hilary" of later records. In the reign of Henry III another Alard was in possession of properties in Leicestershire, etc., and was ancestor of the subsequent St.Hillaries. He was a benefactor to the convent of St.Albans.
