In 1823, in response to growing agitation over tithes, the Composition Act was passed which stipulated that henceforth all tithes due to the Church of Ireland were to be paid in money rather than in kind. This necessitated a complete valuation of all tithable land in Ireland. The results of this valuation are contained in the tithe applotment books which list the names of tithe-payers by townland. Donagheady is one of the very few parishes in Northern Ireland for which there is no tithe applotment book. Why this should have been so is not clear.
Although there is no tithe applotment book for Donagheady, there is, however, a collection of documents in the National Library of Ireland in Dublin relating to the assessment of tithes in the parish (MS 17,990). The first of these documents is dated 9 September 1826 and concerns the nomination by the Rev. Charles Douglas of Earlsgift of Robert Howard Nolan Esq. of Londonderry as his commissioner to fix and ascertain jointly with a commissioner appointed by the select vestry a composition for all the tithe of the parish with the exception of the glebe-lands. The other documents in the collection are certificates of composition for tithes in the parish. Twenty-five of these are from 1833, with a further one from 1834. The table below lists the names of the tithe-payers and the lands upon which the tithe was charged.

The agreements with the Rev. Douglas seem to have been made with either the outright owner of the lands or someone who enjoyed a perpetual lease or a lease for lives renewable forever of them. The townlands of Altrest, Ardmore and Gortmonley were all part of the freehold of Dullerton, though no certificate for the townland of Dullerton is in the collection. No agreement with the Marquess of Abercorn for his lands in the manor of Dunnalong has survived, though that is not to say that one was not drawn up.
