Kerry, maybe just a small amount of help? entering the -USS St. Maurice civil war- without quotation marks some sites will come up. Going down to the 8th site click on it. Once you click on this site going down to #100. There you will see a photograph of the USS St. Maurice.

Terry, comes and goes at this site but he has probably has more experience on naval vessels during the War than anyone else, although he would deny it. LOL

It also may be possible to contact the NARA in DC directly via email and just ask them if the USS St. Maurice is known to have a deck log during the Civil War. If such a log exist it probably would be there.
