It's very possibly the the Graves family lived in Sorel, Quebec before coming to Pittsburgh Township.
Today I was looking at LDS FHL film
1430819 and there is a George Graves born in Sorel and christened in the Anglican Church called
Christ Church. He was born in 1805 which is the right age to have been the George Graves who married Catherine Percy.
I've been doing some seaching on the internet about Sorel, Quebec. There is an article called
The Loyalists of Sorel that says when the time came to divide the land in Sorel among the Loyalists, they were given a small amount of land in Sorel and then the remainder due to them was given at Cataraqui which became Kingston.
Sorel to Kingston is a fair distance, but from other things I've read, the British government was anxious to inhabit their side of of North America to protect it from the Americans.
View Larger MapI did not find a marriage or a death on the film for this George Graves so if it the man who married Catherine Percy, they did not get married at
Christ Church in Sorel.
On the 1852 and 1861 censuses Catherine says her birthplace is Upper Canada. There is a Percy Township in Upper Canada so maybe her family originated from that township, but the township is west of Kingston. Is it likely that someone born as far east as Sorel would meet and marry someone as far west as Percy Township? They would have married about 1820. It makes sense that if this is the George Graves who married Catherine Percy, that they would have been married at her church. I will try to search the neighboring counties to Pittsburgh for Percy names. Perhaps I will get lucky and find what I'm looking for. She could have been a Methodist or Anglican.
In the meantime, I've now got film
199690 of Pittsburgh Township land abstracts ready to go. With any luck I will be able to find something about the Graves family from the land records.
