The Elim Pentecostal Church was founded in 1915 by a Welshman in Monaghan Ireland. George Jeffreys was an outstanding evangelist and church planter. He had a Welsh Congregational background, was strongly influenced by the Welsh Revival of 1904, and was introduced to Pentecost by an Anglican vicar, Rev Alexander Boddy of Sunderland.  Between 1915 and 1934, George Jeffreys conducted some tremendous evangelistic missions. This unknown preacher would commence a mission with a mere handful of people, and by the end of the week, thousands would clamour for a seat. Amazing miracles of healing had taken place.
