Good to hear from you again Kathryn. It has been a few years. I am looking up the information you requested. I have not looked at it for some time. I have been chasing my mother's family (Kelly / Hoey) in Dundalk. Found a couple cousins I did not know I had.
Quick summary; My great great grandmother was Catherine Dwyer who Married Thomas (Mul) Downey in 1832 in Graffin parish of Templemore, Tipperary County. I have birth dates for their four sons that I know of. Thomas had a brother James who married Margaret Howley about 1839. I have birthdates for six of their children, one of which was a Catherine born Feb. 19, 1850. Will forward all info to your AOL address shortly. Also found a connection with the Ryans you mentioned and my Molloys in Tipperary.
