I'm keeping an eye on this thread. There is a possibility that the Griffin family of Cregganbane are related to these people, albeit distantly.
The Griffin family is proving to be the arm of my family tree (www.jag-genes.myheritage.com
) that's proving most difficult to research. I am aware of a distant connection to the Loy family of Cregganbane.
As it happens my uncle, Joe Griffin, settled in Liscalgat when he married in to the Hearty family.
