Ellis Jenkins was born in Church Village and spent his early years in Beddau. Educated at Bryn Celynnog Comprehensive School, Jenkins started his sporting life playing football for Llantwit Fardre, before taking up rugby at the age of 12.
Jenkins played for all the Blues age grades and won the Welsh Championship every year he was in the squad. His performance at regional level saw him promoted to captain of the Blues Under-18 squad and then on to Wales.
He was integral to the Under-20 Junior World Cup team in South Africa in 2011/12, who were the first team to beat New Zealand at Under-20 level, earning them a spot in the semi-final.
Jenkins was captain of the Wales Under-20s team who were runners up to England in the 2013 JWC in France and in 2014 signed a new long-term deal at Blues as he looks to continue his development as one of the most talented and promising young back rows in Welsh rugby.
