1749
From thatch to brick
By 1749 de Britto's thatch could no longer hold the congregation, and Fr Buttari set about a lasting church to replace it. He “laid the foundations” of it, and Fr Thomassini carried it to completion. By the parish's own record it rose in broad bricks, its foundation stone blessed at a kankol festival the parish dates to 1749.
In English
"Fr Bouttari, who baptised Devasahayam… He administered the Christian community of Vadakencoulam and laid the foundations of its present church; he left that country to replace Fr Thomassin in the district of Aour."
What this source establishes
The documented core, and all of it: Fr Buttari "laid the foundations of its present church". Bertrand gives NO year. The 1749 date, the kankol festival and the fabric of the building are all parish-side — which is why this dot is tiered tradition, not documented.
