I found some of the records initially on the Irish Family Heritage Website.You can do a general scan of their records for free, but it costs 5 euros to look at specific records.It's a bit like going to the casino.I am not a gambler, but the Irish Family Heritage website does have a couple hundred euros worth of my worldly goods.
We also visited the Irish National Library in Dublin, which has a microfilm collection of church parish records from throughout the country.The technology is clunky, of course, and the records are very hard to read.Still, we found enough to direct us to Clonmellon.
In Clonmellon, we met with a wonderful parish priest who threw open the parish records, which some army of saints had seen fit to type.There, we found many records about relatives we had never heard of.
The church marriage record for Patrick McGuire and Catherine Fitzimons does not identify their parents.However, the witnesses are identified as Pat Fitzimons and John McGuire.No doubt those gentlemen are relatives as well, but they could be fathers, brothers, uncles, or cousins.
Clonmellon is 17 km east of Collinstown.Google maps says that it takes 17 minutes to drive from one town to the other.
Clonmel is 198 km south and slightly west of Collinstown in County Tipperary.Google maps says that it takes 2.5 hours to make the drive.Ironically, I have a record that my gg uncle Patrick Maguire (Thomas Maguire's brother) was born in Clonmel on 26 March 1810.
