This looks like the perfect opportunity for contact. They have email links and also a discussion board. You may have to look no further!

Just found out they also have a ROSTER on that site:
Good guess, but Bennett wasn't his name though 
That was my other grandfather, who's time in the army during WWII needed no research, he was in the 101st airborne, and is a life time member even though also deceased in the New England chapter. Anyway back to Grandfather LeBlanc, I checked out the above links, unfortunately on the roster there were 2 LeBlanc, not him though. I signed up to be able to post on the 106th message board, waiting for acceptance. Over a month ago found a link to the 106th actual newsletter/site to which you could submit a request to locate someone that served in the 106th, but no response at this time My link. I also sent an email to the New England contact person of American Legion to see what info may have been listed maybe on his application, and also to there general customer service email box, again with no replies. I will keep plugging along
