Hi Cori, it will help alot if you can send us a copy of of his discharge documents, if you can, upload them to the forum or email them to Marion or me.
We need to find which Infantry Division he was originaly was in when he was wounded, he was not with the 351st when wounded.
In you rour post you say he was wounded 7 Aug 44. I seen your message board post on Ancestry.com in which you stated " My Grandfather was also wounded, sent home for a brief time to recover and then sent back."
In this case, he would not have been sent back to his orginal unit. When he went back he would have gone through the system of Replacement Depots and assigned to his new unit ( the 351st GSR) shortly after his arrival back in France.
The 351st is shown on his discharge because it is the last unit he served with.
There may be clues to his original unit in his separation papers.
