(born 5 August 1789, died 29-April-1821 at Hyderabad) (Sometimes given only as Lt. Connor) for Coorg (then written as Codugu or Koorg), Francis Mountford (1790-1824) to Guntur and James Garling (1784-1820) to the Nizam's territories. By 1816 Garling had used a triangulation system similar to that of Lambton to work out the position of the ruins of Bijapur and was moving northwards. While Garling's work was appreciated by the surveyors of Bombay, he was rebuked by Mackenzie whose orders restricted him to the Nizam's territory. The government in an attempt to hasten his move to Calcutta sent the yacht, HC Phoenix to transport him and his family from Madras on 24 June 1816. The captain, Criddle, was ordered to take him to survey the Pulicat and Armegon Shoals before taking him to Calcutta. Mackenzie however set about to his work and did not board the yacht. The government then wrote that he should use the survey ship Sophia which was to bring Sir John Malcolm to Madras in May 1817. He finally set sail to Calcutta on 17 July 1817 aboard Sophia. When Mackenzie moved from Madras to Calcutta, Lechmiah was retained. Death and after He died on 8 May 1821 at his home in Calcutta, India, and was buried in South Park Street Cemetery. His widow, Petronella, offered the collections to the Bengal Government at a tentative price of Rs 20,000. The law firm Palmer and co. did an assessment of the collections and arrived at a figure of Rs 100,000 as a 'reasonable reimbursement' and the Bengal Government acquired the collections. In 1823 Petronella married Lt. Robert Page Fulcher at the Cape of Good Hope. Fulcher was a fellow traveller on the ship to England and her original plan was to move to Stornoway to live with Colin's sister. Mackenzie's Will left 5% to Lechmiah. Much of his collection of documents, manuscripts, artifacts, and artworks is now in the British Museum and the Oriental and India Office Collections of the British Library, though part of it remains in the Government Museum in Madras. Samuel and Hester Johnston's son, Sir Alexander Johnston, wrote a memoir on the life of Colin Mackenzie. After Mackenzie's death, Lechmiah continued to help Horace Hayman Wilson in cataloguing the collections. He applied to the Madras division of the Asiatic Society to continue work on the collections made by his master. This was rejected on
