Dear List,
I am perhaps presenting myself behind time. This is due to my long illness.  However, I want to make it known that I collected some information regarding Narendranath Laha/Law and my source was: 

Samsad Bangali caritabhidhan, 1976. The Chief Editor was Subodhkumar Sengupta, a renowned profeesor  of English, Presidency College. A very rigid person in terms of correctness and insight.

He was the son of a very rich person named Hrishikesh Laha. He passed M.A. from Presidency College,  got Premchand-Raychand  scholarship in 1916 and was awarded PhD in 1922.
