Hi! While seeking the the family home of the Dillons in Knockarley I visited the last Robert Ardill in 1997. Wonderful old 3 story house built in 1600's with pegs instead of nails. (Hence expression - they pegged it out) Kitchen still with dirt floor and big roaring fireplace. Robert had three sisters still living Ida, Eina and I think Blanche. All very ancient and no heirs. This family goes way back in the area but you may be seaching in the wrong county. Knockarley (sometimes listed as Knockarlow) is in Aghancon Parish, Kings Co (Offaly). Look in the 1821 Census at either 'Ancestry' or 'Roots Ireland' to find them and if interested in later Ardill family check out Griffith's Valuations in 1854. Best site is 'askaboutireland' click on Griffiths. Good hunting. Kenvic.
