Isabel and her heirs; for which they bind themselves in an indenture of three parts, one remaining with the said Isabel, another with the prior of the house of St. John the Apostle at Pontefract, and the third with the chaplain. Whenever the Chantry shall be void, the said Isabel, her heirs and assigns, the lords of the manor of Gunthwaite, shall appoint the chaplain, who shall be a secular, not a regular, [i.e., not under the rule (regula) of any religious house], and who shall enter without any other presentation. If they do not present within a month, then the prior of St. John of Pontefract shall present; and if he does not present within three weeks, then four or two of the most able parishioners of Calthorn shall appoint. Neither the Archbishop nor the Archdeacon to have any power or jurisdiction in this Chantry. Three copies of this indenture to remain with the chaplain, Isabel, and the prior, one each."
