Essex County Will Book 12 contains estate administration inventories/appraisals for Anna Fogg Noell and her husband Cornelius Noell. I don't have exact page nos for Will Book 12 because some of my notes are at home and not here at the computer. The estates were administered at the same time (in 1770) though it is not clear that they died at the same time. One of the entries in Will Book 12 suggests that her husband died in 1766 and that she died in 1770, though I was unable to get copies of these documents. The administrator for the estates in 1770 is "Cornelius Noell", probably their son. I will be getting copies at the Virginia State Library in Richmond when I make a trip down there within the next month or so --if memory of my note is correct, it's Microfilm Reel No. 46. (I live in Fredericksburg, VA --45 miles from Tappahannock, Essex Couty, VA, and I just made a trip to review primary sources in the Clerk's Office tothe Circuit Court).
On September 20, 1773, Cornelius Noell and his wife Sally sell Fogg land that devised to Cornelius upon his mother's death that she inherited by will from Nathaniel Fogg (the Bedford Settlor's maternal grandfather). On September 22, 1773, "Cornelius Noell of Bedford County" conveys all of his interest in his maternal grandparents' estates to Reuben Garnett. The Garnetts appear to have been a related family to the Noells (there are Garnett-Noell marriages), but I don't know if Reuben was in fact a brother in law, uncle, or the child of a Noell-Garnett marriage. Elizabeth Fogg, the widow of Nathaniel Fogg and the mother of Anna Fogg is living in 1773 at the time Cornelius sells his claims in the Fogg estates to Reuben Garnett. There is no mention of Cornelius's wife Sally in the Noell-Garnett conveyance. 
I noticed on the Noell page that your line is also Cornelius Noell, the native of Essex County, VA who settled in Bedford County, VA. I would love to share information on the Essex County and Bedford County Noells. The Bedford Settlor's son and grand son moved to St. Louis Missouri, and my maternal grandmother was a Noell in that family. My grandmother's DAR records showed that she thought the Bedford Settlor was born in Essex. I belive the deeds I've found and inventories establish that fact. I'm now trying to figure out the Bedford Settlor's relationship to the Original Settlor Cornelius Noell. My working hypothesis from secondary sources: Cornelius Noell (m. Elizabeth Page), James Noell (m. Elizabeth Owens), Cornelius Noell (n.@1720, a.k.a. Cornelius Noell Jr./Cornelius Noell II, m. Anna Fogg), Cornelius Noell (b@1745 in Essex Couty, m. "Sally" [Miller? from Bedford County? abt 1767?] d. 1820 in Bedford County)
