I know a folk name of a small hill in my hometown. By “folk” I mean it’s only known by inhabitants who have lived there for a very long time (10 years +) or those who have grown up near this small hill.
It seems that there is no official name at all. The folk name sounds quite funny: “the hill of Juju”, Juju being an anonymous guy, maybe an old inhabitant.
Do you think OSM is a place to put this very blurred detail ?
