I'm descended from the Blankenships too - my ggg-grandmother was Elizabeth Anne (Annie) Blankenship, the daughter, I think, of John Blankenship & Millie Thompson (if I recall, she is either the sister or cousin of Miles Green...I don't have my Blankenship file in front of me & offhand my memory is hazy as to who was who...)
In response to your message about Hilliard's Legion: they were organized at Montgomery in June 1862 & had about 3,000 men. Originally, it was comprised of 5 battalions, but one mounted battalion became part of the 10th Confederate Cavalry REgiment. Its artillery arm was detached & redesignated the Barbour Light Artillery. The Legion was assigned to General Gracie's Brigade & served at Cumberland Gap, then at Chickamauga (TN) where it lost 45% of the 902 engaged. In November, Hilliard's Legion was dissolved. Parts of the 1st & 3rd Batt'n formed the 60th AL Reg't & the 2nd & 4th Battn's became the 59th AL. Colonels were Henry W. Hilliard & Jack Thorington. The 3rd Battn' was led by Lt. Col. John W.A. Sanford & Major Hatch Cook. -- The 59th AL was organized at Charleston, TN in November 1863. The Reg't was assigned to Gen'l Gracies Brigade. They served in the Knoxville campaign & lost heavily at Drewry's Bluff & in June, 1864 only had a force of abt 240 men. The unit served at Petersburg & various conflicts around Appamattox. Many were disabled at Sayler's Creek. Later attached to Moody's brigade, the unit surrendered with 9 officers and 101 men. Field officers were Col. Bolling Hall, Jr., Lt. Col. George Huguley, John D. McKennan & Major Lewis Crumpler. The 60th Alamba's service record is almost identical to that of the 59th. (this is from Units of the Confederate States Army, by J.H. Crute, Jr.) -- I recently visited Chickamauga, and Hilliard's Legion, as I was told, was hit heavily, losing about 37% of it's force in just the one assault - it is the only Brigade that made it through Union lines before being forced to retreat (no support). It is difficult to find mention of Hilliard's Legion - but Gracie's Brigade is usually the one noted in publications. Two other ancestors of mine served with Hilliard's Legion: James A. Logan & William C. Kelley. Logan was injured at Drewry's Bluff & Kelley disappeared after Chickamauga - it is believed he was killed in that battle.
My ggg-grandmother, Elizabeth Anne (Annie") Blankenship married R. Major White. Their daughter, Angeline White married James A. Logan, and their daughter, Mary Ella Logan married William H. Smith. (Mary Ella & William Smith are my great grandparents.)
Hope this helps...If I can find anything on Company C will let you know.
