Witches, in the Discworld, occur only in Lancre (apparently)--although Hilta Goatfounder seems to have moved down to the plains, but she's from Lancre. Mrs. Gogol is not technically a witch--rather a Voodoo Priestess, although there seems to be little difference in their ideas and powers.
And of course Granny Aching, who Granny W says is a witch who made the sky her hat.
All witches have acquired some basic knowledge in the areas of medicine (both human and animal), and they are part social workers/part judges in making sure that the right things are done.
Which is exactly why Granny Aching is also a witch. The only difference is she didn't learn witching from anyone else, & her powers were strictly of the headology variety
