Treacy/Tracey/Devilly families

My name is Sean Tracey.  I am looking for any descendants of Devilly's or Treacy's from the Parish of Kilkerrin or the registration district of Glenamaddy.  My GGfather John Treacy/Tracey left in the 1870's and went to Durham England where he married Sarah Duffy.  He worked in the Shotton Colliery as a coal miner.  He emigrated to the United States in 1882.  John Treacy had a sister or cousin named Mary Treacy who married a Devilly and took the land over when her father Laurence Treacy died.  She married a James Devilly/Divilly in the Clonberne Chapel in 1869.  Thanks.
