When I go on a hunt and find a church, I go to great depths into the building, the history, the people etc. The unfortunate fact is I retain it in my brain. When researching, I always end up going off course. Like in the study of St.Aloysius I ended up studying shellac chemistry. Shellac used on the pews. Even George Clarke 1886 who supplied the timber to make them. So it does go too far quite often...
