There is a marriage in Calcutta in 1908 that is probably him. The marriage in 1917 may be him. I cannot tie him to MIC address He may well have changed the order of his Christian names. I have contact an Ancestry Tree owner with only 44 people including a man of this name, to see if I can unravel his life and determine if I have 1 or 2 people here..
