Family info:
In 1698, his father and four of this Pierre's brothers left Port Royal to start a new settlement, along with a friend named Pierre Gaudet. They traveled by boat and eventually decided to settle along the Chipody River. They cleared the land for the settlement and farming, started a gristmill and sawmill, hunted furs, etc. They became friends with the local Amerindians and had a very good relationship with them.

In the spring of 1700, Pierre (senior) returned to Chipdy with his wife and nephew. He spent the winters in Port Royal and the spring through fall in Chipody. Chipody is now known as Shepody, New Brunswick.
