The fate of many transplanted families and their estates can be traced up to the end of the seventeenth century and beyond. The persistence and local influence of some is reflected in placenames such as Frenchpark, Brabazon Park, Mount Dillon, Mount Talbot, Mount Bellew and O'Callaghan's Mills. A number of transplanters or their heirs were prominent in the war in Ireland between 1689 and 1691. For example, Theobald Dillon, by then seventh Viscount Costello-Gallen, raised two regiments for James II and was among the more than 7,000 men killed at Aughrim on 12 August 1691. His wife Mary, daughter of Sir Henry Talbot, fell victim a few weeks later to ‘the second bomb thrown into Limerick by K. William's army’. Thereafter, the Dillon regiment entered French service, where it remained active until its last colonel, another Theobald, was slaughtered by his own troops at the opening of the Franco-Austrian war in 1792. The Dillons were among the numerous Catholic adherents of James II who salvaged their estates either under the articles of Galway and Limerick or by having their outlawries reversed. Subsequently, the implementation of the ‘penal laws’ against Catholics ensured that many of these landed families would conform to Protestantism in the course of the eighteenth century. The seventeenth Viscount Costello-Gallen eventually sold the family's estate of 93,652 acres to the Congested Districts' Board in 1899.
