I realize most of these posts are quite old, however, hopefully some of your emails are still good.In searching for info on my Vincent White who was in Edgefield Co,SC from about 1795 through 1806, I ran across this listing of a Revolutionary War Muster Roll, that he is found on.Vincent White was from Craven Co, NC but fought battles in SC, so your Abney's may also go back to NC.
Because it has a lot of Abney's listed, I thought I would post it, just in case it helps somebody link to their line.

Revolutionary War Muster Roll - Brooks' Company
General Butler's Sister, Elizabeth, became the wife of Zachary Smith Brooks, Lieutenant during the Revolution and afterwards Colonel of State Cavalry. As it may possibly be of interest to some persons now living, I give here the muster roll of a company of cavalry commanded by Col. Brooks while he was still only a captain. I greatly regret that there is no date to the paper, but it is very old. Some of the names I cannot decipher and some are erased:
List of Capt. Zachary Smith Brooks' Company
Zachariah Smith Brooks, Captain
Robert Christie, First Lieutenant
George Pope, Second Lieutenant
Joel Abney, Cornet
John Abney, Secretary
John Abney, First Sergeant
Hardy Matthews, Second Sergeant
Wade Carson, Bugler
John H. Powell
C. Yeheets, Pointer.
I deeply regret that there is no date to this paper; but judging from the names I find and from the quality of this paper itself, it must be full eighty, or ninety, or perhaps a hundred years old. The George Pope, whose name I find as second lieutenant, was a brother of Sampson Pope, grandfather of Judge Y. J. Pope and Sampson Pope, grandfather of Judge Y. J. Pope, and Sampson Pope of Newberry. Robert Christie, first lieutenant, was, I think, father of Simeon Christie, some time Sheriff of Edgefield District. Joel Abney, cornet, lived on Saluda River, near Higgins Ferry, and was the father of Pope and Joel, and the Rev. Mark Abney, who was so well known at Edgefield some years ago. He was the father also of two daughters, Charlotte, who never married, and Elmina, who first married a Dr. Belden. When I first remember seeing her she was a widow. She afterwards married a Methodist minister named Rush. She became a widow again and died in 1889 or 1890, at an advanced age. She was helpless and bedridden for several years before her death. Azariah Abney was a brother of Joel and lived near him. They married sisters - Joel, Elizabeth Pope, and Azariah, Mary - who were sisters of George and Sampson Pope. Wade Carson was of that same family of Carsons; some of whom are living now not far south of Saluda River; and one, Rev. James Carson, is a Baptist preacher. There were three John Abneys; one was the father of Dr. M. W. Abney, whose home was at Edgefield, and who died there about the year 1886. some of the descendants of the others are still living in that section. of the descendants of Hardy Matthews I know nothing, and cannot write with certainty, though the name Matthews is still known in Edgefield, and a citizen of Newberry, E. P. Matthews, went from Edgefield and having found great attractions in that county, married and remained there. And, in the year 1891, Mr. Budd C. Matthews, grandson of a worthy citizen, followed the example of E. P. and married in Newberry and deserted the land of his birth.
The names of Boram, Spragins, Buffington, Hart, Champion, Deshass, Nunn, Eskridge, and perhaps some others on this roll, have disappeared from that part of Edgefield. Of the descendants of Captain Smith Brooks, the most celebrated and best known to the Hon. Preston S. Brooks, who served his country and State, commanding a company of volunteers during the war with Mexico. He was afterwards elected to the Congress of the United States - was expelled from the House for caning Mr. Sumner, and was immediately re-elected. Some of the Willises and others, still live in the same section, not far from their ancestral homes.
