I think I would ignore the 1848 marriage!
December qtr 1848, Devizes has the following names:
Carpenter, Robert
Giddings, Mary Ann
Master, Anne
Tasker, Robert
Tilly, Joseph
Waite, Emily
That's 3 grooms, and 3 brides! Everthing tied up nicely!
Not all marriages (& births & deaths) were registered in the early days of Civil Registration, as there were no penalties for failing to do so!
Like you, I can't find the marriage
