Have you ruled out this bapt?
6 Mar 1808, St Thomas, Dudley
JAMES Wheeler to JOHN/MARY
(FreeREG)
There are several children bapt there to them including a LOUISA 29 May 1814
Father John is a Glass Maker on her bapt.
If they married Dudley there is this Marriage there 28 May 1787
John WHEELER/Mary CHERMAGE
With a bit of googling I can see Dudley is only a few miles from Halesowen.
