Pope Francis has named Bishop Kevin J Farrell of Dallas to head the Vatican's new office for laity, family and life.

The Dublin-born bishop will celebrate his 69th birthday on September 2, the day after the new Vatican office officially begins its work.

The Dallas Bishop Farrell is the brother of Bishop Brian Farrell, secretary of the Pontifical Council for Promoting Christian Unity.

Both brothers were ordained to the priesthood for the Legionaries of Christ, but the Dallas bishop was later incardinated in the Archdiocese of Washington and served as an auxiliary bishop there 2002-2007.
