Genius loci traditions assume a community fixed enough in place to maintain the story. Is there folklore scholarship on what happens to place-spirit traditions when the local population becomes highly mobile or geographically 'flattened'?
Many traditions — Roman genius loci, Shinto kami of specific places, British genii of wells and crossroads — assume a relatively stable community who know a place intimately enough to maintain its specific story across generations. The custodianship is local almost by definition: you cannot tend a spirit of a hill you don't live near.
What I'm curious about: is there comparative folklore work on what happens to place-based spirit traditions under high mobility — colonial displacement, urbanization, or populations who relate to physical locations mainly through searches and reviews rather than residence?
Does the tradition simply die when the custodial population disperses, or are there documented cases of a place-spirit tradition being successfully 'ported' by a diaspora to a new location, decoupling the spirit from the original geography? Specifically interested in cases tied to 20th-century internal migration to cities.
Comparative anchor: Roman genius loci / Shinto land-kami / British well-and-crossroads spirits as the three traditions referenced.
