The inception of the musical foundation

As we have seen, even before the building of the new Castle Chapel was completed, the Castle authorities had begun to plan a foundation that would mirror that of the chapel of St James's Palace in London. This is proved by a previously unnoticed letter in the National Archives of Ireland sent on 14th October 1814 by William Howley, Bishop of London and ex-officio Dean of the English Chapel Royal, to Samuel Slade, First Chaplain to the Lord Lieutenant. Enclosed with this letter was an account of how the choral service was performed at the Chapel Royal at St James's Palace written by William Holmes, Sub-Dean of the English Chapel Royal, and his suggestions as to how a similar (albeit more modest) choral foundation might be established in the chapel of Dublin Castle.

Holmes's letter reported that the English Chapel Royal choir at the time consisted of sixteen gentlemen, ten choristers, a master of the boys, two composers, and two organists. After explaining times of services and duties of various officials, Holmes made the following recommendations:

The quotation marks suggest that this remark was a quotation from Slade's lost original letter to Howley, which was presumably a request for advice as to how the services of the English Chapel Royal might be imitated in the new Castle Chapel. Slade evidently considered these suggestions alongside other members of the viceregal administration, as enclosed with these letters is a document dated 30th November 1814, apparently making recommendations for the personnel of the new foundation:

From comparison with a letter of 1801 in Samuel Slade's hand, it appears that this list was not written by him.
