I wonder if it is the same relative? JPD? I found something from a family note (although very blurry) but if him, for a birth entry for child (not on records found on websites but in newspaper Times of India) it mentions him as a Manager and Waterfall Estate. Couldn't make out the Town/Village name but think its in Niligiri district. Not sure if that is the plantation where he worked or where he lived but worth exploring. Yes, a staffing list would be very helpful.
