Hi
Your 1861 reference shows a Dovey family but the Mary Ann you refer to is their lodger aged 51 and her surname is Badman - not Dovey.
However - in 1871, the same Mary Ann Badman has dropped 21 yrs and is aged 30 with 3 children aged 14, 11 & 8
So you are presumably looking for a marriage between Mary Ann Dovey and ?? Badman and a male Badman death between 1862-1871
