The Cain surname and its variants occur in the biggest numbers in north (Ulster), west (Connaught)and southwest (Munster)Ireland and the Isle of Man. Smaller numbers occur in northern England and south of London. Many migrated to North America & Australia. We hope to provide ancestral roots for Cain/Kane/Keanes throughout the world that we can connect with. For more information:
