Hi Deborah
Here is the marriage you wanted
Jacob Hopgood to Mary Day25th Dec 1824 St.Mary's Alverstoke.
Old style certificate
Married in Church after Banns
Both marked their signatures with a cross
Witnesses James Hopgood and Susannah Kingrove?
Both witnesses marked with a cross.
It's difficult to read the second witness but that's the best I can come up with.
