I am trying to find the correct birth for Christopher Calvert who married Mary Allison in 1788 in Stockton. I have Mary in 1851 living in Northallerton, listed as widowed and a pauper. I believe she died in 1852 in Northallerton. There is a birth of a Christopher Calvert in 1764 in Brompton, Northallerton (death in 1819), born to Thomas calvert and Jane. This seems quite likely to be the correct birth (and death), but I don't know how to make sure.
