Robert Lyle (died 1470) was the First Lord Lyle of Duchal in Renfrewshire.[1] [2] He became a lord around 1438.[3] On July 18, 1452, he witnessed a charter by James II.[4] He took his first seat in Parliament in 1454.[5] In 1464–1465, Lord Lyle was one of the attendants on King James III.[6] For his service, the King granted Lord Lyle a manor, as well as lands in Renfrew.[7]
Lord Robert Lyle was married at least twice. His first marriage was to Margaret, daughter of Andrew, first Lord Gray and likely occurred prior to 1445.[8] The second legal marriage was to Margaret Wallace, with whom he had a son, Robert, and a daughter, Elizabeth, who later married John Stewart of Blackhall.[9]
