John O'Hagan was born in Coalisland, County Tyrone. In 1939 he went to England to pursue a business career, and became known as a woodcarver. In St Michael's Church, West Bromwich hangs his carving 'Madonna and Child'. Another of his carvings was presented to Queen Elizabeth II by Sandwell Metropolitan Borough Council. The artist's family possess his carved chairs and chests which carry the armorial bearings of the O'Neills.
