I have been following this family line for over two years for a cousin in the States. The family links to the De La Durantaye dit Locat and not the Morel de La Durantaye family. The ancestors you mentionned are from Plantagenet, Prescott County, Ontario. Have information about these families: Dufort, Lacarte, Blondin. Definately you are related to my cousin and others that moved to northern Ontario in late 1800's. Please contact directly at email@example.com for more information.
