Jacob Vandiver most likely enlisted in the 11th Georgia Cavalry after the initial Muster dated May 2, 1864 as this is the one and only muster roll for the company and for the other companies of the regiment that survived to be incorporated in the records.

If you have access to a Library holding the Broadfoot Supplement to the Official Records, you can view these rolls in the Georgia volume, Record of Events.

11th Regiment, Georgia Cavalry

11th Cavalry Regiment was organized near Athens, Georgia, in November, 1864, by consolidating the newly formed 30th Georgia Cavalry Battalion and four companies raised under the authority of the War Department where the conscript act could not be enforced. The unit was assigned to the Department of South Carolina, Georgia, and Florida, and served in M.W. Hannon's and R.H. Anderson's Brigade. It fought at Savannah, but many of the men were captured. In February, 1865, only 90 effectives were present and in April most of these were captured at Macon. Colonel Andrew Young, Lieutenant Colonel H.W. Barclay, and Major Madison Bell were its commanders [NPS Soldiers and Sailors System]
