Hello
I can't see the marriage either but if these are the couple in Tutbury taking their children to the Nonconformist chapel I think you have the right marriage.
Joseph 25.10.1806 Gt Barr,William 7.5.1809 Hanbury,David 8.5.1814 ,Job 8.10.1816 ,Elizabeth 18.4.1819,Enoch 24.5.1821,Reuban 14.9.1823 and Mary Ann 13.10.1825.
The 1851 and 1861 censuses give births Joseph Marchington 1784 and Catherine Lullington Derbyshire 1785.
There are christenings for the couple.
Joseph Bannister 10.10.1784 Marchington s of Joseph and Ann
Catherine Holden 14.5.1785 d of Joseph and Elizabeth at Lullington (not on FindMyPast)
The Holdens seem to have come from Walsall and presumably moved back there.
William 2.10.1773 ,Jno Sander 25.9.1776 ,Joseph 23.9.1779 and Jane 28.9.1782 are all christened at Walsall and there is a marriage.
Joseph Holden and Elizabeth Bott 14.6.1771.
Catherine the only one baptised in Lullington.
Does that help ?
