Hello all I need some help with where Derrin, Co. Cavan, Ireland is or was. Some of us believe our ancestors were from there but as of yet, I can't find this particular location. What I am finding is Derrin, Co. Laois, Ireland. But that is no in any remote closeness to Co.Cavan. Is it possible Derrin, Co. Cavan, Ireland no long exist? Kind regards Diana Nowell
