I agree with avm228. Census ages, especially taken over more than one, are more reliable than a death age.
The more instances you find of age given will help you pinpoint your ancestor.
If you trace John Dudley senior from Westminster, you may find his occupation matches that on the marriage certificate.
I am Australian, from all the lands I come (my ancestors, at least!)
Pine/Pyne, Dowdeswell, Kempster, Sando/Sandoe/Sandow, Nancarrow, Hounslow, Youatt, Richardson, Jarmyn, Oxlade, Coad, Kelsey, Crampton, Lindner, Pittaway, and too many others to name.
Devon, Dorset, Gloucs, Cornwall, Warwickshire, Bucks, Oxfordshire, Wilts, Germany, Sweden, and of course London, to name a few.
