Ack, my insomniac fingers have failed me again: that should read
-dóttir, of course.

I see that besides the link on "giants" that I posted, there are a few

International Saga Conference, Major Theme: The Fantastic in Old Norse

In particular, Terry Gunnel's paper on elves which mentions the cult
of ancestors, but also suggests that some souces may have equated them
with the Vanir.

And while I'm posting links, your fascinating post on elves and
angels, Konrad, reminds me that I must get round to reading Alaric
Hall's thesis on elves one of these days:
