Its a bit late for this but here are some details I have found....
I guessed Bryn-y-Maen from your clues and got lucky
Christ Church was built between 1879 and 1899 at the expense of Mrs Eleanor Frost in memory of her late husband Charles Frost. The architects were Douglas and Fordham of Chester in Neo-Perpendicular style. Mrs Frost's commission also included the vicarage and a house for herself.
And with her full name.................
Rhwng-y-Ddwyffordd, a cottage situated between Colwyn Bay and Llanrwst.
When Eleanor was 12 years old she went into service in London (possibly with the Frost family). James John Frost of Shadwell, London, was associated with a rope and cable manufacturing company, and was of considerable means. In 1863 Eleanor married Frost’s son Charles. She was 36 and he 32. They were married in Llanddulas, but by 1874 they were living in a fine house in Min-y-don, Old Colwyn.
Charles inherited a large fortune on the death of his father. He and Eleanor travelled extensively in Europe and the Holy Land. They had no children of their own, but adopted a son and 2 daughters.
Charles Frost purchased a large plot of land at Bryn-y-Maen and in 1895 a mission room was erected on it. Charles died the following year and was buried at this site.
In 1897, Eleanor Frost laid the foundation stone of Christ Church, which was being built in her husband’s memory. The Architects were Douglas & Fordham of Chester, and the builder Thomas Jones of Caernarfon. Eleanor also had built two properties facing the church – a home for herself called Bryn Eglwys, and the Vicarage.
The church was consecrated by the Archbishop of Wales in September 1899, and described by him as ‘The Cathedral of the Hills’.
