The material consists of deeds, wills, marriage settlements, legal searches, statements, opinions, accounts and correspondence relating to the legal and administrative affairs of the Moore family of Moynehall, County Cavan. The documents are primarily concerned with Samuel Moore the elder and his younger son and namesake, who succeeded to the estate as a consequence of the untimely death of his elder brother. Of particular note is the material relating to the case of Moore v Jackson, which provides a good example of the complex set of procedures required to break an entail to facilitate the mortgaging of lands. Also of note are the copies of seventeenth- and eighteenth-century documents, the originals of which may no longer survive; and statements of title such as P15/1/2/1/1 which contain valuable genealogical information of the Moore family across three centuries.
