The Precious Blood Church Fire of 1875 is well described in several places. Stories are found in newspaper accounts and on the internet. They is a fine summary of the stories HERE.
A current project of mine is to find all the vital records of the 70 people that died from that fire. That means the birth, marriage, and death records for all the victims. I am almost done and as of May of 2021 have 5 more birth records and 3 more marriage records. Those that are left are very hard so I will keep trying.
