Here is the image of the James Robinson / Jane Hale marriage on ancestry:

11 Nov 1850. Jane's residence Rose Hill, father William Hale, weaver. Witnesses Samuel Hale and Mary Hale.
William Hale was a weaver on the 1841 census, so it all fits.
D'oh - of course it is the right family, since James and Jane are with Esther on the 1851 census!!!
(edit - thanks, Merry, I know all that now!)
