I have no Cronin DNA matches at all. However the names you mention interest me. My g-grandfather, Michael J. Cronin, came over from Ireland to Whitinsville, MA in 1872 with a Daniel Buckley who was married to a Johanna Cronin. There was also an Ellen Cronin Sheehan in the area, who might be connected somehow to the family. I am speculating that Johanna Cronin & Ellen Cronin might be sisters of Michael J. Cronin's father, Michael. All I know is that Michael J. states in the family bible that he was born in Cork City in 1852. The dates are off but we could be talking about cousins. I will check on the Coachford connection to see if I can find anything that fits. Thank you. Kathy
