Are we talking about the family who live in Ranscliff and have lots of kids? Martha, Samuel, Hannah, John, Eliza, Solomon, Jacob??
If so then all the births seem to be registered in Wolstanton so it is possible the marriage was in that area.
It would help if you can give us some more information as there are a surprising number of Oakes in that area and they all seem to use the same names for their children.
