Virtual Genealogy Lecture  Exceeds ALL Expectations!

Members, Council,  and friends of The O Mahony Society are indebted to local West Cork historian and genealogist,  Margaret Hurley Murphy of the Skibbereen Heritage Centre, for an OUTSTANDING virtual genealogy lecture, "Settlement Patterns of the O'Mahony Clan from the early 1800s" on Sunday, 9 June 2024.  

Record-breaking numbers from around the world joined us for what was a focused, informative perspective on 19th-century O Mahonys in Munster.  Margaret provided updated resources and invited attendees to review the Skibbereen Heritage Centre's list of genealogy resources that includes explanations of what the user can expect as well as resources within resources (e.g., Griffith's Valuations).  Better yet, stop by and take advantage of a fabulous West Cork resource! (

Comments from participants included, "This lecture has been so helpful and [I] can't wait to start searching again," "This was a wonderful virtual event," "This was SO interesting!  Thank you so much!!!" and "The past few years' lectures have really raised the bar; wonder where they'll go next!"

The lecture was recorded but needs a little editing.  It will be posted to our Publications/Lectures tab as soon as possible. 

2023 Gathering at Rath Raithleann

Our first post-pandemic picnic and rally at Rath Raithleann was a fair, fun, enjoyable, and engaging day where we had experiences never before had, thanks to speaker Prof. Billy O Brien!

It only took four years, but we were finally able to meet in person for our 2023 Gathering!  

The weather forecast for June 23-25 was far from promising, but the good Lord was good to the O Mahonys. Not only were we not washed out, we also had a FANTASTIC weekend!  The Society owes a debt of gratitude to Council member Pat O Mahony, who coordinated an outstanding slate of speakers for our event.  Our guest speakers included Rory Bunce of the Cork County Library Local Studies Library, who was a featured Genealogy session speaker, and Professor William (Billy) O Brien, Chair of the Archeology Department at UCC, who is an expert on Rath Raithleann, this year's rally site.  His fascinating lecture can be seen by Society members via the YouTube link found here.   Additionally, we hosted our very first hybrid AGM!  Many thanks to Council members Bill Badzmierowski and Catherine Carbino for providing much-appreciated traditional Irish music as members arrived for the meeting.  Full details will be forthcoming in our next Newsletter!



IN MEMORIUM:  John W. Mahoney

It is with profound sadness that we share the news of the passing of  Council Member and Genetic Genealogy Project Co-Administrator John W. Mahoney of Albany, California, on 19th February 2024.  John and his wife, Mary Ann's joyous laughter could always be heard at our Gatherings and his generosity and gifts to the Society were many, profound, and deeply appreciated. 


John, with Mary Ann's support, was still actively working on contributing to the Genetic Genealogy Project and our annual Journal whilst undergoing treatment in the hospital.  Per Mary Ann, he always loved being a part of The O Mahony Society.  Per the O Mahony Society, we were lucky to have him, his quick but always kind wit, and his many contributions. 

Please join us in sending sincere sympathies and the very deepest condolences to Mary Ann and the family. 


With thanks to Dan Mahoney of Rockville, Maryland, we had fantastic weekend in the Albany, New York area for our October 2022 North American Get Together.

We are extremely lucky that Dan is stepping up to the Get-Together organizing plate again.  In the near future, we will be posting details on another North American Get-Together, the kick-off event for our 2025 70th O Mahony Society Anniversary year-long celebration!
