A peerage title as Earl of Fingall was created in 1628, by King Charles I of England, and granted to Luke Plunkett, 1st Earl of Fingall, Baron Killeen, whose first wife, Elizabeth Plunkett "née" FitzGerald, thus became Lady Killeen The Plunketts also intermarried with the Prestons, Viscounts Gormanston. The Fingall Estate Papers, acquired by the Fingal County Archives, do not however relate to any properties in Fingal, but rather to lands in Meath. That Fingall title became extinct upon the death of the 12th and last Earl in 1984, along with a peerage barony of the same name, not to be confused with the titular prescriptive barony of Fingal previously mentioned.
