Griffith Family IN CO Kilkenny CO Carlow

I am looking for information on the Griffith families in and around Coolcullen in Co. Kilkenny and over the border in Co. Carlow around Ridge and Old Leighlin.

Specically - anything to do with Lewis Griffith and his wife Elizabeth. I estimate their births as about 1770. The lived in Ballasallah and Knockalane.
