Well, it took a couple of months and lots of sleuthing, but we finally found out where Barack Obama's Irish roots are from in the old country: Moneygall.
It was a combination of U.S. census records and tombstones that led me to zero in on Moneygall in then-Kings County, now County Offaly. I conducted the research in my capacity as Chief Family Historian for Ancestry.com, and enlisted the help of Irish expert Kyle Betit of ProGenealogists.com once I had a location. Then it was a matter of finding out exactly where the records we needed to solve the mystery resided today. That's where Canon Neill came in, as the records turned out to be in the possession of one of his parishioners.
At any rate, am heading off to London for the Who Do You Think You Are LIVE! conference (that should be fun, eh?!), so don't have time to share many details now, but I'll leave you with this vital (though admittedly hard to read) clue from the research!
