I see your posting is old, I hope you come back to visit it.
My Regan's are from Drinagh West as it has been told to me. Julia Regan married Jeremiah Murphy. The witness' were James Murphy, bro to Jeremiah and William Regan assuming brother to Julia. Jeremiah and Julia would be my gr. gr. grandparents. It was again told to me that a Regan relative is living in one of the two homes on the road that leads to the Old Drinagh Cemetery.
Hoping to hear from you.
