Charles Stuart, 12th Lord Blantyre, (21 December 1818 – 15 December 1900), styled Master of Blantyre from birth until 1830, was a Scottish nobleman and landowner with 14100 acre of titled lands. Born at Lennoxlove House, he was the second son of Maj.-Gen. Robert Stuart, 11th Lord Blantyre and his wife Frances Mary, the second daughter of the Hon. John Rodney, younger son of Admiral George Brydges Rodney, 1st Baron Rodney. In 1830 at the age of only twelve, he succeeded his father as Lord Blantyre. Stuart entered the British Army and was commissioned into the Grenadier Guards. He was appointed a Deputy Lieutenant of Renfrewshire in 1845 and was elected a Scottish representative peer in 1850. On 4 October 1843 at Trentham, Staffordshire, Blantyre married Lady Evelyn, the second daughter of George Sutherland-Leveson-Gower, 2nd Duke of Sutherland, and had by her five daughters and a son, Walter, who predeceased him. Lord Blantyre's wife died in Nice in 1869 and he survived her until 1900, dying aged 81 at Erskine House, which subsequently became Erskine Hospital (now a hotel, renamed Mar Hall). The Lordship of Blantyre became extinct on his death.
