Paul, On the website-Confederate Soliders Burried in ILL. Their is a William Boswell Snead who was a Private in Mclintich Batt. Va. Artillery CSA. Birth 1820 and Died 1885. Grave L6 B9 GHS. I was wondering if this your William Boswell ? If this the service records may help. They will show where he inlisted and maybe more. Hope this will help.I didn`t know if you had this information.
