Bev its also worth trying two other things.They may have Travelled around The Neighbouring Counties .Although we Cant find much.One of the Children May have also Stayed Nearby.Contact Kilkenny Library,They hold Local records.
message the archivist.Most Libraries are very helpfull.I helped a friend Recently.With Family in Urlingford. And the Islands.We eventually Found two of her Ancestors.It took a few Weeks.
So Dont go giving up just yet.Something May still turn up.Its also worth Checking The IRISH FAMILY HISTORY FOUNDATION .I did add some of the records they hold in a previous message
