Thanks so much Gig! I have ordered that book.
I also checked my prior communication with my DNA match and he is from Michael and Honoria Kennedy, then Michael b 1819, then John b 1831, then Bridget b 1881. I have many ancestors from different parts of Ireland and some others even in North Tipp.on my grandmother's side. But this DNA match shares other matches with me (2nd and 3rd cousins) along a clear and distinct family line of Ryan's from Latteragh. He matches my brother and I at 4th cousin level which is a strong match at high confidence level. I was excited to find him!
I was in touch with someone who was documenting all the stones at Glenkeen last year. He stated that he couldn't find these Ryan's there but that he confirmed they were there from a local descendant. He did stumble upon an area where a stone was laying on the ground and was hard to read and he had thought it could be theirs for some reason.
There was an article in the Nenagh Guardian around 1900 when the Ryans were renewing their pub license that stated the Ryan's had held a license there for 4 generations. Another article from the 1860's had a Michael Ryan working in the pub. A fairly common name...but who knows..maybe it was your Michael b 1798!
