Miles, thanks! Here is what I have on the two soldiers not in the book.

Joseph Granget aka Joseph D. Grange and Joseph Granger - Believed to be former Confederate with Companies B & K 10th Regiment, Louisiana Infantry. Ewell's Corps; Johnson's Division; Nicholls' Brigade. Confederate CMSR's list him as being about 23 years of age when joining the Confederate unit in July of 1861. He was present for every battle the 10th Regiment Louisiana participated including his last at Gettysburg. Just to list a few of the battles he was present at were Malvern Hill, 2nd Manassas, Sharpsburg, (Antietam) Fredericksburg and Chancellorsville. He was listed as being from Saint Landry Parish, Louisiana. Although his name is spelled all three ways on his Confederate CMSR's the most common was Grange and Granger with only one page showing Granget. His name is listed on his title page as Joseph D. Grange. He was captured during the Gettysburg campaign and while a prisoner at Fort Delaware was desirous of joining the Union Army and turned over to Lieutenant Colonel Tevis who was forming the 3rd Maryland Cavalry. Union CMSR's have his last name as Granet and have only one page as Grangers. The now blue uniformed soldiers of the 3rd Maryland Cavalry left Baltimore in January of 1864 for duty in Louisiana. While boarding the steamer for Louisiana in Baltimore, Maryland, young Joseph D. Grange or Granger simply vanished. He was listed as deserting in Baltimore, Maryland, never to be heard from again.

Peter Stanton - Believed to be a former Confederate with Company A 10th Regiment, Louisiana Infantry. Ewell's Corps; Johnson's Division; Nicholls' Brigade. Confederate CMSR's listed him as being born in Ireland and enlisting in the Confederate unit in July 1861, at age 29, and was a laborer prior to the War and living in New Orleans, Louisiana. Confederate CMSR's also list him as a prisoner during the Gettysburg campaign and being desirous of joining the Union Army and being transferred to the 3rd Maryland Cavalry at Fort Delaware. 3rd Maryland Cavalry CMSR's list him as being born in Ireland and being a laborer prior to the War and enlisting at age 30 in September 1863. His physical description was 5' 7" in height; blue eyes; dark hair and dark complexion and may not have been able to write as he made his mark with a X. Union CMSR's also report him as deserting the 3rd Maryland Cavalry on July 24, 1864 at Carrollton, Louisiana which is close to New Orleans, Louisiana. He does have a Declaration of Recruit papers showing being desirous of joining Union Army and also enlistment papers in the 3rd Maryland Cavalry signed by a X, his mark. He was taken as a prisoner to Harrisburg, Pennsylvania and then to Philadelphia, Pennsylvania and then to Fort Delaware. The stragglers and deserters for the majority of the Confederate prisoners during the Gettysburg campaign followed this particular route. Those taken as prisoners during the battle would generally go to Fort McHenry and then to Fort Delaware.

I'll check on these other names and let you know what I find and again thanks for your help!
