I am interested in discovering more about John Langtree (sometimes written as Lanktree),
b. 18April 1806 and d. 16May 1876.
He left Ireland some time after 1851 for Australia, having been employed as a Land Agent and having written "The Elements of Land Valuation ..." 1853. Find A Grave locates his burial at Carlton, Melbourne City Cemetery and provides further detail about his Irish parents and his family. Any help will be appreciated.
