My John Dalling (1801), according to the 1851 census for Sussex, Kings Co, New Brunswick, Canada, immigrated to St John, St John Co, New Brunswick, Canada in 1820. On one census record the Devon, England is followed by a question mark (Devon, England?). His land petition is of no help because he is one of 28 on the petition, he settled in Waterford, Kings Co.
His birth year does not vary, it is 1801 on all records.
The John in Oare, Sussex interests me , he is the son of William and Frances, his oldest son is William and second daughter is Frances. He married Mary Chambers and their second son and oldest daughter are her parents names. Is that wishful thinking?
I met Johnny Dalling on my last trip to NB, the Dallings' still own the same land, they think Devon.
