Exactly! I should probably let you know that I'm trying to help my electrician find his roots. He's really in better shape than most of the famine descendants, many of whom are not even sure of the county where their ancestors were born. When they hear that I know the exact places and a number of my cousins living in Ireland, their loss is painful. I try not to let my luck be known. However, this man has something to go on so I'll try to help him out.
His great-grandfather did marry in the United States. They know where he was married and the names of his parents. If I can't come up with anything on my own, I'm going to have him recheck the church records and civil records there to see if there's anything else that might have been missed. I'm also going to have him delve into the records of siblings, if he knows of any. Maybe the cemetery might have something too. Usually, if you can't get it one way, you can come at it from another direction.
I've been eying Fuerty myself and that's a civil parish as well as a townland, but some of your other suggestions have possibilities too. The birth date of 1822 is too early for some parishes to have records available and the LDS doesn't have it or the names of his parents with other births in their database, but if he's really lucky, it could be in one of the Roscommon microfilms in the National Library.
How I wish the officials in the U.S. didn't accept just Ireland as an answer. That wouldn't fly today.
Thanks again. I'll keep you posted if anything solid comes up, and if anyone else has any suggestions, I'm all ears. This one has me stumped.
