Lindsay, Robert (1679–1743), lawyer, was the elder of two sons of Robert Lindsay of Loughry, Co. Tyrone, and his wife, Anne Lindsay, daughter of John Morris of Bellville, Co. Tyrone. He succeeded to the Co. Tyrone estate of his father on the latter's death in 1691. He was educated at Drogheda and entered TCD in 1696, graduating BA in 1700. He entered the Middle Temple in London in 1703 and was called to the Irish bar in 1709.
He became a friend of Jonathan Swift (qv), who conspicuously excepted Lindsay from his general disdain for lawyers. It was probably on Swift's recommendation that he became counsel to the proctor of St Patrick's cathedral, Dublin, in 1722, and seneschal (or legal adviser) to the cathedral in 1724. Swift may also have introduced him to Vanessa (Esther Van Homrigh (qv)), to whom Lindsay gave legal advice. Two of Swift's Drapier's letters in 1724, addressed to the Chief Justice William Whitshed (1679–1727), may reflect the legal knowledge of Lindsay, though the attribution of the letters to him is not accepted by all authorities. Two published pieces of verses are attributed to Lindsay, one on the profession of the law, to which Swift composed an answer, and another in the form of a dialogue between the two friends. Their connection was enduring, and Swift in his last will of 1740 named Lindsay as one of the executors.
He sat in the Irish house of commons for Co. Tyrone (1729–33), when he was appointed a justice of the court of common pleas. He married Elizabeth Singleton, daughter of Edward Singleton, MP, and his wife, Catherine Newtown, both of Drogheda; one of Elizabeth's brothers was Chief Justice Henry Singleton (qv). The couple had a son, who died young, and a daughter, who died unmarried. Lindsay died in January 1743 and was succeeded by his brother, John Lindsay (1686–1761).
