The girl in the far right photography has a half-bang on the right side, like the mother of half-bang in the previous page. I think that confirms that half-bang's mother was a former resident of the church. There's also a baby star nun in that photography.
Edit: looking closer, that's not a photography, that's a charcoal drawing, with half-bang's mother face as signature on the top left corner, so it's confirmed that she was in this church before.
