Dear Everyone;Thank you for your suggestions. I contacted my patron, and gave her the copy of the lyrics.
She says it's a lovely song, but she's sure it isn't _the_ song. (There is some family tradition about her relative indeed being buried on a snowy day, and therefore she is (fairly) sure that "bury me away on a snowy day" was an accurate rendition of the lyrics.) I've wondered, and suggested to her, if it might be a regional variation of the same song.
We both very much appreciate your responses.
Laura Staley
