Looking for Carragher's of Corratanty

Hi,

I am looking for anyone connected to the Carragher/McArdle family of Corratanty. I know there were Carraghers in Castleblayney and Carrickmacross but I don't know how (or if) there are connected. Specifically, my second great grandfather was James Carragher and his wife was Catherine McArdle.

Looking forward to connecting with you all.
