They were found by local businessman, Jonathan Ruff, and his team. Talking to Express, Mr Ruff said the discovery had been made working on renovating the church, knocking down an extension from 1972 that they needed to rebuild.
When it was knocked down, one of the workers noticed a tin with a note inside from 1977, which explained that, due to inflation, it was not possible to remove the stones.

Mr Ruff first posted the images of the bricks and letter to Facebook on Tuesday, with commenters offering their thoughts as to the origin of the mystery bricks.
One commenter on the post said that she had been a churchgoer since the 1950s and recognised the names.

Though Mr Ruff said they currently have no definite lead on who the bricks belong to, he said they were in contact with the Head of Jersey’s Catholic Church to find out.
If no one is found, the stones will be moved to the other side of the Church, to be put alongside the other stones already in place.
