There were (2) books published in 2000 by McGill-Queens University Press in Ontario regarding the Petworth emigration during the period 1832-1837.
The Tribe family, of which I am also a descendant, was part of this emigration. The books are, Assisting Emigration to Upper Canada - The Petworth Project 1832-1837, and English Immigrant Voices - Labourers' Letters from Upper Canada in the 1830's.
The first book gives detail on who funded the emigration, who was selected, the routes they took, where the families came from in England and where they settled in Canada. It also has a brief family history of the families that came to Canada.
The Laborers' letters I have found fascinating since they describe the trip over, the conditions they travelled in, the land and experiences they had.
It appears there were (2) different Tribe families involved with this emigration; my line was Henry Tribe of Sussex, his wife Charlotte, their unmarried children, and at least (3) of his married children, including his married son, Benjamin.
There are also other Tribes: George Tribe, wife Sarah Heather, from West Sussex, James Tribe, Shiddingfold, Surrey, John Tribe, James' brother, Thomas Tribe, uncle of John and James. There is no indication that these families were related.
