Struggled to find any details re: parents of Mary though I can confirm their marriage took place on 30/1/1826 in St Giles.
The marriage was by Banns, Mary was of this parish and Thomas, sojourner (though I've no idea what this is).
The witnesess were John x Andrews and Elizabeth Smith and J.B.
Unable to locate any WISE surname from 1788 - 1820. Went back on the marriage index to 1769 but no WISE marriages. Couldn't find any children from the marriage though I could only manage the St Giles books so they could have been baptised elsewhere
Sorry couldn't help anymore
