I live near Greenville Sinsull.
My father originally came from Donegal and my Grandmother came from Bridge of Weir in Scotland, I don't know if the Geese are a part of either place's folklore and until I read Strupag's post I hadn't really thought about that evening in a folklore context, more of a spiritual one but I will ask my Dad when I speak to him and see what he has to say about it. I have heard Seal folklore still alive and being told in Ireland and in the Western Hebrides in Scotland. Selkies..(seals) are the souls of the departed and there are many stories and songs about them.
