In the "Discworld" amongst the duties of a witch are midwifery and laying out the dead. If possible, people call Nanny for the former and Granny for the latter. In effect Nanny and Granny make a perfect team with Granny doing what needs to be done and Nanny bandaging the wounded. Indeed, in "Thief of Time", Nanny Ogg is sought through various timeframes as she is/will become the best midwife in the world, perhaps evinced by her statement that she has even served as midwife for entirely non-human species like Trolls.
