Above: The 1838 St. Augustine Church of Rustico is very similar in design to Saint-Phillippe et Saint-Jacques. The main church measures 80 feet long by 50 feet wide not including the tower or vestry.

Above: The 1839 St. Patrick's Church of Grand River is very similar in design to Saint-Phillipe et Saint-Jacques and St. Augustine Rustico. However, it's hard to see the similarity in this image of St. Patricks today. The original church, built between 1836 and 1844 (consecrated in 1839) was 60 feet long by 40 feet wide. In 1890 the church was redesigned by well-known Island Architect Wm. C. Harris. The original plan of the church was enlarged, a new steeple was built; false butresses added and Gothic windows installed on the upper wall in the balcony. Photos of the original church exist, however, I don't have access to them at this time.
