I just notice this thread because I'm going to be posting a related question for St-Bonaventure-d'Upton and now I have a question regarding this "refreshing".
Does anyone know what happens to the remains that were originally in the repurposed/refreshed grave?
Are they somehow disposed of or reburied in a mass, unmarked grave elsewhere in the churchyard?
What happens to the headstone assuming there had been one?
I never knew the Fre-Can Catholics did such things as "repurposing" the graves of the ancestors. You learn something new all the time.
