Bio: Silas Evans was born in 1864 in the village of Pencarreg near Llanybydder in southwest Wales. His university education took place at Saint David's College, Lampeter, where he graduated with a B.A. in theology in 1885. 

He served as a cleric in the Anglican Church in Wales. He was a curate in Dyserth, in Rhosddu and in St. Asaph. He was Vicar of Cyffylliog in Denbighshire between 1901 and 1909. In 1909 he became Vicar of Llanrhaeadr-ym-Mochnant in the Berwyn Mountains between Bala and Oswestry. He became a canon of the church in 1928. He developed an interest in astronomy and was a Fellow of the Royal Astronomical Society for a period. 

He wrote an English-language popular book on astronomy called "Marvels of the Sky" (publ. A. H. Stockwell, London, 1931, 97 pages) and a compilation of 'astronomical sermons' called "Ad Astra" (publ. A. H. Stockwell, London, 1931, 80 pages). He is best known as the author of the Welsh-language book about astronomy "Seryddiaeth a Seryddwyr" (publ. William Lewis, Cardiff, 1923, 323 pages). He also wrote a history of the parish of Llanrhaeadr-ym-Mochnant in Welsh, "Hanes Plwyf Llanrhaeadr-ym-Mochnant" (Gwasg Gomer, Llandysul, 1940, 87 pages), and a set of religious meditations "Myfyrion Min yr Hwyr" (Gwasg Argraffwyr Abertawe, Swansea, 203 pages).
