I believe that 1841 was the first of three marriages for Stephen, the next in Sep Qtr 1848 and the last in Dec Qtr 1865.

So if I understand ~ your believed sequence of events are as follows ;
Stephen Price mrd Ann John 1841
++ Ann is buried 1845 or 1847
(Note ; From my book on the headstones of Park Street Cemetery I note that there is an headstone to an ANN PRICE. The memorial reads : To the memory of / ANN PRICE/ Who departed this life Sept 26th 1841 / Aged 56 Years. This Ann appears to old to be the late wife of Stephen and my research appears to indicate it is the wife of James Price of the Dock)
Stephen Price mrd Margaret Brace 1848
++ Margaret Price buried 1851 or 1858
1861 Stephen resides in Monkton
Post 1861 ~ Stephen moves to Prospect Place P.D.
Stephen Price mrd Elizabeth Griffiths 1865
Stephen & Elizabeth remain in Prospect Place
Stephen Price is buried in plot B. 268 Llanion Cemetery 12 Feb 1895
Elizabeth Price is buried in plot B. 268 Llanion Cemetery 28 Oct 1899
(Note ; Neither Stephen or Elizabeth left a will)
The only other point to be made is that any children after Emma noted are not baptized established church, which would appear to indicate that the family at some point converted to N-C.
Am I anywhere near to your findings ??
