I have been researching my families genealogy for over 20 years and have run into a few brick walls. I am looking for any early records of the Salls family, who relocated to near what is now Clarenceville in the 1780's or 1790's. Specifically, I have been unable to locate death records for my 7x g-grandfather, Isaac Salls and his wife, Hannah (Hawley), as well as any records that my give a hint as to the identity of Hannah's parents. What I know, is that Isaac and his wife Hannah arrived near Clarenceville sometime in the 1780's or 1790's, along with their son, Jacob Salls, Jacob's wife, Margaret and children, George and Phoebe. A year or 2 later, 2 other sons of Isaac and Hannah arrived, Hix Salls and Abraham Salls (my 6x g-grandfather). My 5x g-grandfather, Abraham Jr was born there, sometime about 1799 and married Malinda McCoy.
Specifically, what I'm looking for are any records of birth, marriage or death of these early Salls', especially pertaining to Isaac and Hannah, Abraham Sr, Abraham Jr. The only records I've been able to find online are land petitions starting in 1795, then the marriage record of Abraham Jr in 1826.
I was hoping to make a trip this Summer to research these things myself in person, but due to COVID-19, it doesn't appear likely for quite some time yet.
I am also curious about the Salls family headstones from the St George Anglican Church in Clarenceville. I understand that the cemetery grounds were being redone and all of the early Salls family's headstones were being stored in the basement of the church. I was wondering if they've been restored to the grounds, or if they were still in the church basement. if they are still in the basement, I was wondering who I may contact to possibly obtain photos of the stones.

If someone could look into these records, I am willing to pay for research time, as well as for copies of records/photographs.
Are you aware of this:
Memoranndum of the First settlement of Clarenceville village and vicinity - By the Rev M Townsend March 30 1850, as verbally reported to him by George Salls
In the year 1781 , Isaac Salls, of Long Island, being a loyalist, was forced to leave his home, when his farm and all his property which he could not carry was confiscated by the American authorities, to seek the protection of the British government and set he face towards the British province of lower Canada.
He was accompanied by his wife and his son Jacob and wife, who had one daughter Phebe ( afterwards married Gamalist Little) and one son George Field Salls (who was born on the journey,), the present narrator.
For the purpose of aiding him in clearing land in the wilderness, he brought with him three men as labourers, named Amas Curtis, David Wilcox and Stephen Wilcox. The party ascended the Hudson to Albany and then to Skenesborough (Whitehall) at the head of Lake Champlain . Here they found the British Sloop of war, the Maria, commanded by Commodore Steel, on board of which they all embarked and on the first of June 1782 they landed at Ash Island in the Chamblee ( Richelieu) River.
At this time the lands on the east side of the river were owned, in seigniory, by the French officers names Foucault and Noyan to whom, ot to their families, they had been granted by the gouvernment of France, previous to its conquest by England and whose names they still bear.
Frearing to be disturbed on the banks of the river by the war which continued between England and the United States, the said Isaac Salls placed the party under the guidance of a party of Indians, who conducted them five miles into the interior, to their own encampment where now is the village of Clarenceville.
About a year after 1783, David Tryon and Josephus Vaughan were added to the settlement , which was partly on each seigniory. Isaac Salls's residence was on the spot occupied now by the Clark's Hotel . His son Jacob's residence was on the farm now owned by G W Johnson. David Tryon'S farm was the one now owned in part by L Simpson. Josephus Vaughan's farm was that owned by Enoch Curtis.
About one year afterwards that is 1784, two other sons of said Isaac Salls, namely Hix and Abraham who had been settled and married from Albany, came with their families to join the infant settlement. Hix Salls took the farm no 14 Noyan, and built the house now owned by E Johnson Smith and Abraham Salls took the farm no 17, 5th concession Foucault, now owned by Jasper Schutt. About this time settlements were formed on the banks of the river by H Ruyter, on the Cutting Farm, Major D Cameron ( on the Mayo farm), A Friot, John Dewar (on the McCallum farm) E Filer , John Griggs ( on the Steel farm) . After this year the settlement increased more rapidly and generally.

One must take exception to this particular verbal story or 1850 - while the whole can be taken on good faith it must be remembered that George Salls is now 79 years old and is not recounting a history, but a family story.
For one the Seigniory of Foucault was not at the time of that the event occured in the possession of the Foucault family, but had been leased by Col Henry Caldwell, from James Murray. ( see indenture to Jacob Salls )
In 1850 we are able to refer to the United States, but at the time Isaac Salls moved to Lower Canada, the name was not in use.
The British Sloop , Maria was sailing from the British fort at St John, not Ash Island where they were no facilities what so ever
The indian encampment was not that of the location of the municipality Clarenceville as it is today, but somewhere a bit south of that location where a freeman's tavern would have stood at one time ( see map )
The last paragraph mentions those names who had the farms in or about 1784, then goes on to mention the names of the owners by 1850 ( see map )
The Clark's Hotel referred to in this memorandum, was replaced by the Magasin Geneal owned by Gilbert L'Ecuyer by 1913.

Just noticed your question after two years (!).

Hannah Hawley and Isaac Salls are my 6th great-grandparents. I am trying to clear up some questions about the Salls and Flaggs and Branch families in the Clarenceville area as well.
