Henry Cloker, like Nicholas Gibson, was a member of the Grocers' Company but his family were closely connected with the Coopers', his father, John Cloker, being Master in 1533 and 1535. In his Will, dated 1573, Henry left two houses in the City to the Company, the major part of the proceeds from which were to be used to augment the salaries of the schoolmaster and the usher at the Ratcliff School. Responsibility for the upkeep of the houses lay with the Company but in the case of any default, ownership of the houses passed to the Grocers' Company. The Will also stipulates that a sermon be preached by a learned man and that part of the Will describing the bequests be read by the Parson or his Deputy at an Annual Service to be held on New Year's Day. This Service of Commemoration of Henry Cloker has recently been expanded to include Thanksgiving for the lives of the other Benefactors of the Company. It is now held in October each year at the Church of St. Magnus the Martyr by London Bridge. The Will is read by the Clerk and the music is provided by the Choir of the Coopers' Company and Coborn School. Attended by the Master, Wardens and Court of Assistants, and by the Master and Clerk of the Grocers' Company, the Cloker Service is one of the main Company functions to which all Liverymen receive an invitation.
