Pierre Berthelet

Real estate transaction records show that he was the largest property owner in Montreal by 1820.

The importance of Pierre Berthelet to Canadian economic history stems from his success in the transitional economy in which he flourished.

A son, Antoine-Olivier Berthelet, was to continue in real estate and take the family into Lower Canada politics.

His son-in-law, René-Joseph Kimber, married to his daughter Appoline, also was active in politics, elected to the Legislative Assembly of Lower Canada.

Another daughter, Cécile, was briefly married to Michael O'Sullivan, but died young.
