On Thursday 13 September 1866, the Lord Bishop of the diocese consecrated the burying ground belonging to the Church at Vochriw. Several of the local clergy were present. A drenching rain was pouring down throughout the ceremony.

During September 1880 the following was reported in the 25 September edition of the Merthyr Express

The Mission Church at Vochriw  The mission church is progressing; the congregation as well as the number of communicants is steadily increasing. At the request of the respected vicar of the parish, a “parochial committee” has been appointed to look after the “temporalities” of the church, and to assist the clergy in their manifold duties.

Prior to the winter of 1881/82 repairs were carried out on the building which cost £20.2s.61/2d and to defray this cost various activities took place amongst which was a  Christmas Tree and Tea party which raised £15.

As part of the annual Sunday School Treat held in July 1882, a German Band under the leadership of Herr Von Nesset entertained. The cake for the occasion weighed 290 lbs and was provided by Mr G Phillips the grocer.

In the Report by the Select Committee on Education dated 8 May 1866, Appendix 5 advised that, in the National School at Pentwyn,  there was a licensed room in use as a church which held 2 services and a Sunday School on the sabbeth with an average attendance of 36 children, whilst the adult membership was 12.

A noted diligent member of the church was Miss Harris of Pleasant View who, around 1886, presided at the harmonium, sang and recited much to the delight of the congregation, before leaving to take up the post of assistant mistress at the Hay National School. Her sad departure was highlighted by a testimonial during which she was presented with a "handsome floral album with illuminated address".

The first newspaper report of entertainment being held at the church schoolroom was in June 1887 and this entertainment continued to be a feature there. It was last reported on 9 January 1915. The entertainment was during the winter months and consisted of local people performing songs, recitations and the like.

St Andrew's Church was rebuilt in 1907 and in later years Mrs Olive Evans presented it with a stain glass window in memory of her parent.

The Merthyr Express reported on 5 November 1910 that the Vicar warmly congratulating the Pentwyn people for their noble work in renovating the old Church. It was a voluntary work, a labour of love.
