Hi Sherbertrose,
I fully sympathize with your situation, having met with it many times in my own family!
Unfortunately from our point of view, the reality is that not everyone baptised their children, then as now. The reasons behind our inability to find specific baptismal records were manifold and included disinterest, an inability or unwillingness to pay the fee, poor record keeping on the part of the parish clerks, the refusal of the minister/clerk to record a baptism because the fee was not paid. Often, if the child was the first born to a couple and they lived outside their family's parish, the infant would taken back to either the mother's or father's parish for baptism.
None of this helps you find what you seek, but may help to explain why you can't uncover Grace Glover's parents.
Did Grace and her husband have children? If so do you know whether or not any were named for his parents and siblings? If some were, then you might be able to extrapolate that one or two were also named for Grace's parents at least. That might give you a clue as to where to look. Do you have any access to Pudsey's parish registers? Perhaps you might find other Glover children who were born and baptised around the same time (give or take ten years or so) with names involved similar to those of Grace and John's children. None of this allows you to know for certain who Grace's parents might have been, but such evidence would be suggestive.
Perhaps Grace's parents were non-conformists around the time that she would have been baptised.
Were any elderly Glovers still around in 1841 dwelling in Pudsey? Depending upon when in their life-cycle Grace's parents had her they might only have been in their 60s at the time of that census. Were there any other Glovers in Pudsey in 1841 or later, more or less of Grace's age? Could there be naming clues among any such persons?
I hope that some of this helps.
Best wishes,
Anne
