The marriage recordof Hannah and John tells us:
Marriages solemnized in the Parish of Almondbury (All Hallows), Yorkshire 29 February 1836:
John Leak of Holmfirth, son of Edmund Leak a clothier and his wife Sarah, baptized 31 December 1815 at Holy Trinity.
Hannah Bradberry of Holmfirth.
in the presence of John Leake and Joseph(?) Bradbury.
A search at Ancestry on Hannah Bradbury tells us that
1) a Hannah Bradbury was baptized - born to James Bradbury and Ann Whitely - 26 March 1815 at Holmfirth. Source: Family History Library/FHL Film Number: 990703.
2) a Hannah Bradbury was born 4 January 1816 (baptized 27 January) at Holmfirth at a non-Conformist and non Parochial church (non-Anglican) to Job and Hannah Bradbury of Newfield in the township of Austonley and Parish of Almondbury.
THe UK 1841 Census indicates that #2 Hannah Bradbury (of Austonley, Almondbury, Yorkshire) is unmarried in 1841 and living with her mother Hannah and siblings.
I suspect your Hannah is #1. (She also happens to have a brother Joseph who was born in 1813 ). The witness at the wedding.
James Bradbury was born about 1795 at Holmfirth. He married Ann Whitely 10 May 1813. I think Hannah's siblings are Joseph, James, Ann, and Jonas...perhaps more.
Hope this helps a bit,
