Donald Hugh (or Hughy) Grant was born in 1870 in the town of Negapatam (Nagapattinam). Unlike his father, he worked for the South Indian Railways as an engine driver (now known as loco-pilots) and later retired as a loco-foreman from Donakonda Junction in Bezwada (Vijayawada).
We gather that he worked in the Madras and Southern Maratha Railways which was then, a branch under the South Indian Railways.
On 19th October 1891, Donald Hugh Grant tied the knot with Flora McKenzie at Trichinopoly (Trichy)
We understand that Donald Hugh Grant led a prosperous life travelling across South India (Vizag, Donakonda, Trichinopoly, Hubli ) in his official capacity before moving to Bangalore, after retirement.
