Second, I have been driven mad by trying to remember or find a book or book series I read as a child, late 90s/early 00s but could have been published much before that. My memory is so sparse: it follows the happenings of a Catholic family with quite a few kids (like 4-5??). It’s very white bread and not very dramatic. They go to a school I believe called Sacred Heart. Could have even been a major plot point. It *may* have taken place in Pittsburgh? Please someone release me from this curse.

It sounds like Too Many Murphys by Colleen O’Shaughnessy McKenna, which was the first in a series about the family. The author is from Pittsburgh.

Beany Malone was set in Denver so not that series.
