I found nothing in the book on "Nancy Hackney". Could Nancy possibly be a nickname? I have found this a few times.
Here is information from the book, page 37. I hope it is what you are looking for.
Elias Adkins s/o Hezekiah and Molly Levon Adkins; b 1797 on the Sinking Creek Montgomery ( Giles-1806, Craig - 1838 ) Co., VA.
As a ten year old child Elias, with parents and siblings, moved to the Raccoon area of the Beech Fork of Twelvepole, of what is today Wayne Co., WV. The area in Kanawha Co., at the time became Cabell in 1809, Wayne in 1842 and West Virginia in 1863.
Elias m CC 25 Nov. 1819 Susanna Fry b 1801 Montgomery (Giles) Co., VA d/o George and Kiziah (Mallory) Fry II. There is much discussion as to whether Susanna was the daughter of George II or George III. The "History of Giles Co." by the Giles Co. Historical Society did not list Susanna as a daughter of either one, however, that should not bother researchers as the editors of this publication made many such errors.Early on I had placed her as a daughter of George III based on the fact that many carried her as the sister of James and David Fry-proven sons of George III. In 1985 I found a statement in the Lambert Papers by "Uncle Hiram Adkins" that "Susanna was a first cousin to Parker Milliton Adkins because Parker's mother was a Fry." Parker's mother was Mary Fry d/o George I and sister to George II. In 1986 the grave of Susanna's mother, Kiziah, was located by Clinton Mays. He took a picture of the stone and sent it to me. I then knew without doubt that Susanna was the daughter of George II. I had prior to this located a CC land record showing Jessee Adkins selling land to Kiziah Fry clearly proving her in the area. If Susanna was nother daughter why would she have been there.After discussing this with Evelyn Massey she found in 1830 CC record of this same land and Susanna was listed as a daughter of Kiziah.
Elias and Susanna left the Beech Fork area of present day Wayne Co., ca 1835 to move to the Hart's Creek area of present day Lincoln Co. This area near present day Ferrellsburg was in Logan Co. until 1867. Elias and Susanna are probably the original settlers of Ferrellsburg. They sold most of their Wayne Co. land in 1835 to Hiram Adkins-CC deed bk 5 pg 469. The last of their Wayne Co. land (57 1/2) acres on the Trace Fork was sold in 1841 to John Adkins CC deed bk 8 pg 136. They are also recorded with Elias' brothers and sisters fiving the main home place of Elias' parents to Hezekiah Jr. This land was transferred in 1842-CC deed bk 8 pg 294. Other records of Elias selling land in CC are for land in the Guyan River area of Lincoln Co. Because of this early move to the Guyan River area this branch of the family was considered as an unrelated branch.
Elias and Susanna appear on the 1820 and 1830 CC census,on the 1840-50 & 60 Logan Co. Census and on the first census of Lincoln Co. in 1870.
Elias was a farmer and Genseng digger in the Ferrelsburg area of Lincoln Co. He d ca 1870 and Susanna d ca 1873. They are bur in the Ferrellsburn Cem. at Ferrellsburg, Lincoln Co., WV. This cem is located on the knob behind the post office in Ferrellsburg.
