Sorry, my question 'Where do you have his place of birth as Newton, Montgomeryshire' - I meant where on the records of James Powell who was in Chapel Hill did it indicate he was born in Montgomeryshire. As Osprey has indicated it is more likely to be James who was living in a neighbouring parish, unless of course you have evidence to the contrary.
I've checked the Chapel Hill registers & there would appear to be only James Powell around at that time, so who would that burial be in 1824 other than the husband of Esther?
I don't understand why with this family in Chapel Hill, Monmouthshire you are looking at records from Montgomeryshire, about 90 miles away or so.

I am beginning to think I have made a 'rookie' linked in record mistake. I am building my tree from use of Family Search, WikiTree and occasionally Ancestry (when free). When searching for James Powells records through Family Search, I believe I pulled a Christening record for James Powell March 1777 Newton, Montgomeryshire, Wales - added it to the 'created' father of Edward Powell (1814) and returned a different day with time, to expand. Thus I may then have located Birth and subsequent death in Montgomeryshire of this James Powell.
I appear therefore to have morphed the wrong James Powell to the tree. Certainly my ancestor was a James Powell re Edward Birth Record (with mother Esther).
Osprey - I will work on the details you feel more likely (which make sense) and see if I can progress.
Thank you both, to this point, as I am learning from your experienced senses with searching
