Hello Bethany. I have a book: "Through Twenty Preston Guilds: The Catholic Congregation of St. Wilfred's Preston", published 1993. No author stated but it may have been Leo Warren . I got it this year in Preston.
It states "... Chapel then situated in a courtyard opposite the present Sun Hotel. This courtyard is known as Old Chapel Yard, off the western side off Friargate between Edward St. and Marsh Lane, formerly Bridge St."
Chapter 3 has the heading "In a certain street called the Fryergate". That chapter is about the "new" Catholic chapel, opened 1761.
Appendix includes: Friargate Chapel Subscriptions 1815.
The Parish Dead of WW1 & 2.
There are chapters on 19thC Preston's R.C. schools. Also extracts from SVP & other church organisations' records.
