Pierre de Rastel de Rocheblave

He helped found the XY Company in 1798 and looked after the Athabasca department as a wintering partner.

Rocheblave purchased land at Coteau-Saint-Louis on the island of Montreal and elsewhere in the province.

He was named a justice of the peace for Montreal District in 1821 and also served on various commissions.

In 1827, he was elected to the Legislative Assembly of Lower Canada for Montreal West.

Another daughter, Mademoiselle Elmire de Rocheblave danced at the Citizens' Ball in Montreal with the Prince of Wales (later King Edward VII) when His Majesty visited Canada in 1860.
