Sir John MacLean, F.S.A., died at his residence, Glasbury-house, Richmond-hill, Clifton, on Tuesday. He had been in very indifferent health for some time, and has been confined to his room with an attack of influenza. Sir John MacLean was a son of Mr. Robert Lean, of Trehudreth, Cornwall, where he was born in 1811. His mother was a daughter of Mr. Thomas Every, of Bodmin. His descent is traced from a branch of the Scotch Clan Lean, and in 1845, with his brothers, he resumed the original prefix of "Mac." He married in 1835 Mary Billing, eldest sister and co-heiress of Mr. Thomas Billing, of Lanke, Cornwall. In 1837 he entered the Ordnance Department of the War Office, and became deputy auditor in April, 1865. He resigned this post on a pension, and received a knighthood in January, 1871. Sir John was the author of several historical works, including "Life and Times of Sir Peter Carew," "Letters of Sir Robert Cecil to Sir George Carew," and "Memoir of the Family of Poyntz."
