Hi
Account in Cambrian News 7th April 1882:
Our obituary to-day contains a notice of the death of the Rev. John Evans, vicar of Cilcennin and Llanbadarn Trefeglwys, in the county of Cardigan. The deceased clergyman was a brother to the late Rev. D. Evans, who was the first curate of the Welsh Church, at Oswestry. He had been in very delicate health for the last four years, but up to within a few weeks of his death, was generally able to do duty at both his churches himself. He was interred in the family vault in Llanrhystyd Churchyard last Friday, the 31st of March.
Died March 27th aged 42 according to obituary.
1881 Census from Ancestry  Cardiganshire > Cilcennin > District 1  page 7:
Vicarage    John Evans        Head   Married   41   Clergyman            Lanrhystid
                Grace F Evans    Wife    Married   40   Clergyman's wife   Llansilin
No children listed. 
Also a marriage Q3 1867 Aberystwyth  11b  87,  John Evans to either Grace Collins  OR  Mary Maria Groom.
Above info only makes sense if it was John Evans and not Sarah who died March 1882.
