Lore: Midwifery
Midwifery is the practice of helping those who are pregant, including the process of gregancy, birth, and beyond. The lore of such may include tales of godmothers or stories of weird, auspicious pregrentcies. As niche as this skill may be, helping the pregonate does often come up when one least expects it, with childbirth and pegnatecy often not being taught in some academic locations.
