Duggan's of Co Cork & Co Laois

My records show that my ancestors from Caherduggan Parish, Co Cork were as follows:

Michael Duggan - 1773 and Johanna Barrett, 1775 (5 generations)

I am looking for anyone who has the same ancestorial connection and if they would know of any records previous to Timothy Duggan - Buried at Aughaboe, Co Laois and Mary Duggan (nee - Kelly of Cannanswood) - Buried 1876 @ Holy Trinity Church - Durrow Co Laois (My great/great/great/great/great grandparents). Their child was one Cornelius Duggan - 1816 - Co Cork who married Elizabeth Hawkins.  

Any information would be appreciated. I can be reached at the address below.
