I noticed something. Freckles Nun's papa has a pompadour-style hairdo, and on a note it's says that he wants (or being drawn by Freckles Nun herself) a bigger pompadour. It's makes me think that, if we follow the timeline a bit later or early, she lived around the 60s at the earliest or the 50s at the latest before moving away to the convey. And grew up to be a full nun by the time of the 1970s. (which means JC-ish Little Nuns (and froggy/hook-bang and hungry/gluttonous nuns) could have been living in the latest 70s/early 80s as the main timeframe of the series.
