Early life Johnston was born in Carnsalloch, Dumfriesshire in Scotland to Samuel Johnston and Hester Napier, daughter of Francis Napier, 6th Lord Napier. Johnston moved with his family when his father obtained a posting in Madurai under Lord Macartney in the Madras Presidency in 1781. Alexander received his early education from Christian Friedrich Schwarz, the missionary as well as under Sir Thomas Munro. He could speak Tamil, Telugu, and Hindustani languages from an early age.
