Do not know Peter Cooney's Parents names OR that of Margaret Dunne's...Believe they were from an area referred to as "Caurgh OR Craugh" Ireland in either County Sligo or County Roscommon or County Galway...Both Mary & Martin immigrated to Massachusetts, USA. before 1866...that's because Martin married in Chicopee, Mass. USA. a Martha Harrop from Cheshire, England on 7 Jan 1866, with Mary Cooney as a witness.
