I didn't really know where to put this and as I would like as much input as possible, so this forum seemed as good a place as any.

I have a newly forming pet theory regarding house spirits; being that they may not soley be tied to the place but often to family from domicile to domicile and generation to generation. Now I have considered this may be a modern phenomena (after all we have recently spoken of deity moving with the times, why not elementals and fae?), however I distinctly remember a story in W. Jenkyn Thomas' Welsh Fairy book of a brownie that liked the family so much it moved with the family. This of course peaked my interest.

So I am sending out a plea, to aid me in my task, does anybody else know of stories/mythology/fairy tales of house spirits/lare/wights/<insert relevant name here> who are tied to families rather than places?

Any help in my research would be gratefully recieved
