A Compendium of Irish Biography/Barnewall, Nicholas, Viscount Kingsland
Barnewall, Nicholas, Viscount Kingsland, was born 15th April 1668. The family had been ennobled by King Charles I., 12th September 1645, for loyalty to his cause. Before Nicholas was of age he married a daughter of George, Count Hamilton, by his wife Frances Jennings, afterwards married to the Earl of Tyrconnel. In 1688 he entered King James's Irish army as captain in the Earl of Limerick's Dragoons. After the defeat of the Boyne he was moved to Limerick; and being in that city at the time of its surrender, was included in the articles and secured his estates. In the first Irish Parliament of William III. he took the oath of allegiance, but upon declining to subscribe the declaration according to the English Act, as contrary to his conscience, he was obliged to withdraw with the other Catholic lords. In February 1703, he joined with many Irish Catholics in an unavailing petition against the infraction of the Treaty of Limerick. He died 14th June 1725, and was buried at Lusk.
