As written in W. Arnot Craick's Port Hope Historical Sketches:
"Owing to the unfortunate destruction by fire of the first Roman Catholic Church in Port Hope, all the records which could throw any light on the early history of this congregation have been lost. It was destroyed by incendiaries one evening in August 1851 and completely destroyed. The Town Council offered a fifty pound reward for the apprehension of the perpetrators of this outrage, but the guilty parties were never brought to justice."
The present building, the Church of St. Mary, Star of the Sea, was dedicated on 07 Oct 1855. The original cemetery was to the southwest of the Church, and the earliest burial records are of 1849. The date of the opening of the present Roman Catholic cemetery on Toronto Road, to the north of Union Cemetery, is uncertain, but as in-town burials ceased in 1874, it must have existed at that date.
In the photo on the right, dated 1878, the cemetery can be seen to the left of the Church (centre). The tower in the background is that of the First Presbyterian Church.
