Seems like these names have com up lately on the lis. I found a description of a Manuscript of personal and family letters of Armand DUPIEREUX at the Green Bay Area Research Center - 1855-1907 in the special collections department. The correspondence is described as being about life in northeastern Wisconsin and includes letters from Civil war soldiers. Other writers include MINSART, and LEVASSEUR surnames. Green Bay SC 61. Hope this helps, Rita
