Thank you so much for your help. This is a pretty difficult project so far.
There is a post on Ancestry.http://boards.ancestrylibrary.com
About the Willson and Lawrence, and many other families who all left the Miramichi in 1793, and it included the Kendricks, formerly of Gagetown and Peter Long and his family. They had 7 children, born in N.S. and N.B. As far as I know, they were the only black family on the ship that left N.B. for Upper Canada.
I figured Peter Long might have met Davidson on the St.John's when Davidson was commissioned to cut masts for the Navy during the Revolution. It looks like the families left when Davidson died.
Peter appears in one petition in N.B. , I have a copy of it.
I have 2 possibilites for Peter's arrival from Massachussets, to the St. John's River. Maybe he came as a slave to a settler from Mass (in which case his name might not be recorded) or he might have come on a British ship at the beginning of the Revolution, such as the 1777 ship you mention. Many blacks served on board ship.
I read that small private ships did patrol the St.John's to protect against Rebel raids, since the Navy could not really send much.
I forgot to mention, in a different petition Peter Long claimed to have served in a Fencible Regiment, but I have not been able to find his name on a muster. Peter Long was literate, and he seems to always work on ships.
His wife Sarah is even more elusive. I have no maiden name for her. She might have been from Gagetown. She seems to enjoy a very close relationship with the Kendrick family from Gagetown. Her place of birth is also elusive.
The family had some children baptized in Church of England in Upper Canada.
The origin of the Kendrick is alwo interesting. Father John was a soldier in a British regiment who settled in Gagetown sometimes in teh 1760s. His wife was Dorcas and they had at least 4 sons and 1 daughter. A S.P.G. missionary baptized the youngest children, twins and noted that they were born in a canoe on the St.John's river.
The Kendricks left N.B. for Upper Canada in 1793, and they got land in Town of York (Toronto) and built ships and houses. They also captained ships.
Joseph Kendrick is the one who wrote the petition describing Peter's service on the St.John's River, and being a ship Captain, he gives a lot of details about the ship. I am pretty sure there was such a schooner Nova Scotia with Captain London, but what I would like to know if whether Peter Long was a civilian, or a Fencible on that schooner.
I am guessing I will have to visit the Archives in Halifax, but that will have to wait.
Thank you again for all your help. Context is so important to figure out a story.
