His grandfather James Arthur Ferguson joined the British army too and took part in World War II.

After the Second World War, Arthur Ferguson retired from the army and took up a job at the India Isabella Tea Estate.

After returning to Lobhachhara, Ferguson crossed over into India taking his mother's permission.
