I cannot seem to find any information of my great-uncle.I have only a picture and a small note that reads, "KIA in Iwo Jima Feb. 19, 1945."As well as a photo of his grave marker at the San Francisco VA cemetery.The marker reads, Corp. Edward E. Erb USMCR and then the numbers 35 20 29 (which by the way I have no idea what they stand for). I have no idea how long he was in or anything. I believe he entered from either Kansas City Missouri or Colorado.I know, not a lot of helpful information. But I am new at this and no idea where to look or where to star. I don't even know what information is available to me. Hope someone can help!
