the above message is superfluous as you'll get those verses if you look up 'Shule aroon' as the first respondent suggested. Of course, now you have some without bothering to search the DT.
If my memory is correct, the Buttermilk Hill version is supposed to refer to a battle in Pennsylvania? If that version does date from the American War of Independence rather than from the Civil War, I don't think Illinois would figure. Well, if we keep the thread going, maybe someone will come up with more concrete information.
bye for now.
