Marquis de Montcalm
Ottawa Citizen confirms that the Marquis who unveiled the statue was a descendent of the Louis-Joseph de Montcalm, Wolfe's opponent at Quebec. There is a man, Georges Savarin de Marestan, who is an, almost, direct descendent of Montcalm and has impersonated him at various reconstructions and become good friends with a descendent of Wolfe. However Marestan is too young to have been the Marquis de Montcalm that unveiled the Greenwich statue in 1930. Perhaps it was his father.
