[3] Around 1833, Belleque settled his farm, which lay next to Étienne Lucier, a fellow former French Canadian fur trapper for the HBC.
There Belleque and his wife, Genevieve St. Martin, lived at the Willamette Fur Post near Champoeg.
[3] On March 22, 1836, he and 15 other French Canadians on the prairie representing nearly 80 settlers and their children signed a petition to Norbert Provencher, the Bishop of Juliopolis, requesting a priest for the settlement.
In 1843, at Champoeg, Belleque participated in the debates over whether the settlers in the region should establish their own government, or wait until the Oregon boundary dispute was settled.
These were Xavier Ladaroute, Joseph Gervais, Pierre Belleque, Francis Bernier, and David Donpierre.
'"[7] Pierre Belleque would remain at his farm for 15 years, and then left for the California Gold Rush in 1848.
[3] Returning home by steamship in 1849 from San Francisco, he became quite ill from a fever contracted in the Gold Fields.
