Earl Tylney

Earl Tylney, of Castlemaine in the County of Kerry, was a title in the Peerage of Ireland. It was created on 11 June 1731 for Richard Tylney, 1st Viscount Castlemaine. The family descended from the merchant, economist and colonial administrator Josiah Child. On 16 July 1678, he was created a Baronet, of Wanstead in the County of Essex, in the Baronetage of England. He was succeeded by his son from his second marriage, the second Baronet. He briefly represented Wareham in the House of Commons.

He died childless and was succeeded by his half-brother, the third Baronet (the son from the third marriage of the first Baronet). He sat as Member of Parliament for Maldon and Essex. In 1703, he married Dorothy, daughter of John Glynne and his wife Dorothy, daughter of Francis Tylney of Tylney Hall, Hampshire. On 24 April 1718, he was raised to the Peerage of Ireland as Baron Newtown, in the County of Donegal, and Viscount Castlemaine, in the County of Kerry, and in 1731, he was created Earl Tylney, of Castlemaine in the County of Kerry, also in the Peerage of Ireland. In 1734, Lord Tylney assumed by Act of Parliament the surname of Tylney in lieu of Child. His eldest son Richard Tylney, Viscount Castlemaine (d. 1734), predeceased him, without issue, and Lord Tylney was succeeded by his second son, the second Earl. He was a Fellow of the Royal Society. On his death in 1784, unmarried, all the titles became extinct.
