The Registry of Deeds, held at King’s Inn in Dublin, was established in 1708 and is the repository for memorials of deeds and conveyances representing transfers of property in Ireland. It was not compulsory to register deeds or conveyances with the Registry, so their records are not a comprehensive account of all land transactions in the country. The Registry of Deeds can be useful for genealogical research because deeds and conveyances can sometimes contain valuable genealogical information, such as names, occupations and addresses for the parties to the deeds as well as family relationships, maiden names of wives and the names of siblings and the married names of sisters. Marriage settlements or the distribution of an estate based on the instructions of a will (which may no longer survive), can contain a great deal of genealogical information. Not all families will have registered transfers of property with the Registry of Deeds, so this source is really only useful for researching families who were in possession of property in Ireland in the 18th and 19th century. John Grenham’s Registry of Deeds information pages on his website provide more information.
