I was born & raised in Knowlton & know for a fact that there are two cem's in Knowlton. There is St-Edouard's Catholic & the Knowlton Protestant a.k.a. Wheeler Cem. Both of these cemeteries are on St.Paul's Rd.in Knowlton.
I've included many more names than what are listed on Interment.net having found they original church records on Ancestry.com. The list you posted was from the Protestant Cem.
