Coxes of Cox Creek Footnotes

Last week, footnote 23 referenced a court case between Alexander Wells and the heirs of John Decker. I attempted to obtain a copy of the entire court file. Since Brooke County is in West Virginia, I reached out to West Virginia to see if they had it. They did not. They did suggest that I try the Brooke County Clerk or try to find it in Augusta County, Virginia. For now, I’ll save the response in my files. If I decide I really need it, I will reach out to Brooke or Augusta County.

28. Deed Book, Washington County, Pennsylvania, IC, p. 283. This document can be found on FamilySearch. This transaction is between Isaac Cox and John Decker for a 400 acre parcel of land known as “Mingo Bottom”. The transaction was for six hundred pounds and was made on July 9, 1778. It was witnessed by George Cox, John’s son-in-law, and presumably two of John’s sons. Which Isaac Cox this land belonged to is not quite clear–George’s father or his brother.

29. Ibid. I, p. 1. This document can be found on FamilySearch. It details the transfer of a parcel of land identified as “Rich Hill” situated in Yohogania County from Gabriel Cox (Isaac’s son) to a James Logan for 1000 pounds of current currency. The transaction was completed on July 7, 1781, however it was not recorded until January 1, 1782. Gabriel was identified as a Justice of the Peace for Washington County.

30. Crumrine, op. cit., Pamphlet VII, p. 391. October 25, 1779, the Court of Yohogania County granted Isaac Cox the right to relocate to Kentucky County, Virginia.

31. Boyd Crumrine, The History of Washington County, Pennsylvania (1882), pp. 229, 239. This book can be found on Internet Archive. This passage refers to a letter from Colonel Marshall detailing the issues he was experiencing in 1781 organizing the militia after Pennsylvania and Virginia came to an agreement on the border dispute. The Virginians, led by none other than General George Rogers Clark were disruptive to say the least. Lieutenant Colonel Gabriel Cox, under the orders of Colonel Pentecost, committed a number of “outrages” against Pennsylvanians who were drafted into service under General Clark but refused to report for said service. Lt Col Cox’s men seized and destroyed property, threatened women and children, and held residents in confinement. Some individuals were ordered to be hanged. (Penn Archives, Series 1, Volume 9, pp 343-345, found on Ancestry.)

Page 239, mentions charges levied against Gabriel Cox in 1782 during the Court of Quarter Sessions for the acts committed on the residents mentioned above. Charges included assault and assault and battery. He was found not guilty of the two charges of assault. After the first two acquittals, the charges were dropped in cases 4 and 5. In a nutshell, Gabriel did what was ordered of him…he was to assemble troops for General Clark. Brute force probably should not have been employed in the process. Since the boundary between Virginia and Pennsylvania (extension of the Mason-Dixon Line) had not been completed at the time, Gabriel ideally should have kept his activities south of that line. Those that filed charges against him, were residents north of the Line. (Penn Archives, Series 1, Volume 10, pp 80-82, found on Ancestry.) It does sound like Gabriel was involved in some form of rioting after the acquittals.

The Centennial Celebration of the Organization of Washington County, Pennsylvania (1881), printer, E.E. Crumine, p. 49. This book is available on Google Books, however, I did not see anything on page 49 that would be relevant to the Cox family.

Additional Findings–Washington County Deed Books

  • Gabriel Cox and his wife Sarah Enoch Cox witnessed a land transfer between Abraham Morgan and Samuel Irwin on May 27, 1783 in Washington County, PA.1
  • Isaac Cox sold a parcel of land in Yohogania County to Andrew Nye for sixteen hundred pounds on August 16, 1779.2
  • Isaac Cox sold a 1000 acre parcel of land to James Ellison located on Plum(b) Run which branches off the Salt River and is about 40 miles from the Falls of the Ohio (present day Louisville KY). This transaction is dated November 29, 1777. Based on the description provided, this parcel is located in the Spencer and Nelson County area. In 1777, it was part of Kentucky County, VA.3
  • On February 9, 1778, a transaction between Isaac Cox and Garrett Vinnaman for land about six miles from the tract he sold to James Ellison.4
  • On March 30, 1778, Lemuel Davis was bound to Isaac Cox as an apprentice. Lemuel was eight years old and was bound to Isaac until he reached the age of 21. Seeing as how Isaac Cox relocated to Kentucky in 1780, it might be necessary to look for subsequent papers regarding this arrangement to see if Lemuel accompanied the Coxes to Kentucky or if his apprenticeship was transferred to someone else.5
  • February 9, 1778, a transaction between Isaac Cox and John McDowell for land in the same area as Garrett Vinnaman.6
  • Gabriel Cox sold land on Hard Bargain Creek to James Swolivan on September 22, 1777.7
  • Isaac Cox and James McMahan were briefly in a trading company partnership with several other gentlemen. The trading company was located about a mile outside of Pittsburgh. Isaac and James sold their shares to Dorsey Pentecost.8
  • This document was witnessed by both Isaac Cox and Gabriel Cox in 1787. Their location was noted as Nelson County, Virginia. This would be the younger Isaac since his father had died in 1783.9
  • On October 9, 1780 Gabriel Cox served as administrator to the estate of Thomas Cook in Yohogania County.10

AI Tasks

When I started on footnote 28, I discovered that the Washington County deeds included grantor and grantee indices from 1781 to 1924. Since the Cox information was split up alphabetically by given name, I decided to enlist CoPilot to help me combine all Cox grantor entries into one table. What I am learning about these AI bots is that you have to treat it like a 3-year old and provide directions for each step in the process. For example, in the past I have learned that you have to limit the number of files and/or size of the files uploaded at one time for processing. So my plan was to upload this is batches of 5 files at a time (I had 24 files to sort). I assumed that I could just upload each batch of 5 and CP would know what to do. WRONG! I took a step back, applied the same prompt to each batch, making each batch a separate data table. Then I instructed it to combine the 5 csv files that were generated.
