I don't know from where in Ireland these people came.His name was WILLIAM DUNNIGAN, born about 1811, son of JAMES & ELISABETH ? He married BRIDGET MCGURK, daughter of AUREN & CATHERINE ?. They died in Great Barrington, MA. he in 1878, she in 1889.I have found both of their grave sites.I am trying to find out where in Ireland they came from & who their parents were. A relative says one daughter was born in County Monaghan, Ulster, so perhaps that is where Bridget was from. Ring a bell with anyone?
