Marsha,
The Illinois Civil War Project at http://civilwar.ilgenweb.net has a regimental history for the 41st, plus other information; i.e. photos, scrapbook, burials; that people have submitted.

If you don't find the burial there, try looking on the IL Christian County Genweb website. Sometimes these have burials listed, sometimes they have people who will do lookups for you for free (brief lookups). You can also post a message on that site.

Hope this helps.
Ann
