About Alexander Elphinstone
"Alexander, seventh Lord Elphinstone, was baptized in the kirk of Stirling 30 March 1647. Being only seven years old at the time of his father's death, Sir Robert Elphinstone of Quarrell was appointed his tutur-dative, the nearest agnate, Alexander Elphinstone of Warthill, having renounced the office of tutory. The estate being much burdened with debt, it was resolved to sell part of it, and accordingly the lands of Airth were disposed of to Captain Alexander Bruce for 38,000 merks. Lord Elphinstone appears to have been delicate, and did not live long. His will was made 10 May 1669, and he died the following day. He married, 10 September 1667, Anne, daughter of Alexander Burnet, then Archbishop of St. Andrews. She was married, secondly (contract dated 20 August 1674), to Patrick, third Lord Elibank, with issue."
