  • Hello Pamela,

    That is a reference to the townland of Garryadeen, which was located in the civil parish of Grenagh. A Google Map shows that Garryadeen, by the shortest modern day route, is 18.5 miles southwest of Castletownroche:

    In a book by Brian Mitchell called, "A Guide To Irish Parish Registers," one of the Catholic parishes located in the civil parish of Grenagh, was also named Grenagh. According to the National Library of Ireland, the Grenagh Catholic Parish baptism and marriage registers begin in 1840. See:

    The 1854 Declaration of Intention for John Herlihy that you attached, shows he was born on 24 June 1826, which means there would not be a baptism record for him in the Grenagh parish registers or a marriage record for his parents.

    There was also another Catholic Church Parish in the civil parish of Grenagh, according to Mitchell's book. This was the Catholic Parish of Mourneabbey. This parish has baptism and marriage records back to 1829. These parish registers would also commence too late in time to have recorded John Herlihy's birth in 1826.

    Go to the following Library of Ireland link to see the availability of the Mourneabbey Catholic registers, and to also view a Catholic Parish map, showing that Mourneabbey is just north of the Catholic Parisdh of Grenagh:

    Another Google Map shows the locations of Garryadeen, Grenagh, and Mourneabbey in County Cork:

    For a Google Street View of rural Garryadeen, go to:

    The Catholic Church in Grenagh is called St. Lachteen’s. Some references give the name of the church as St. Laghteen. This is a very old Catholic Church. According to the National Inventory of Architectural Heritage/Buildings of Ireland website, the church of “St Laghteen’s” was built circa 1820, and so may be the church where John Herlihy was baptized. For a description and slide show of the church, go to the Buildings of Ireland link at:

    For a Google Street View of the Church, go to:

    Earlier, on a Google Map you saw the locations of Grenagh, Garryadeen, and Mourneabbey. The map shows that Garryadeen is much closer to Grenagh than to Mourneabbey, and so it is likely that the church in Grenagh was the church that John Herlihy and his family attended. Because St. Laghteen’s predate John’s birth, it is possible that he was baptized there in 1826.

    You can view the “R.C. Chapel” in South Grenagh on an Ordnance Survey Map from the 1837 to 1842 time period at the GeoHive website link:

    For an ordnance Survey Map of Garryadeen from the same time period, go to the GeoHive link at:

  • Dear Dave,

    You are terrific!! Thank you for all this useful information!

    My William Herlihy Family line is from Killavullen and I am trying to figure out if he and the John Herlihy mentioned in the record are related. I was told they were, but the two locations seem a bit far apart and so not likely brothers but possibly "cousins". John's parents were Jeremiah Herlihy and Elizabeth Callahan so I will have to do some investigating and see if I can find any records. However, as you stated the dates are getting a bit early for some of the churchs. 

    Thank you again. 


    PS Are you all have a bad experience with the Corona virus? I live in the New York City suburbs and it has been very bad here. Everyone I know has been following the rules and so far have been safe. Scary times but lots of time for research... a silver lining if you will. :)

  • You're welcome Pamela, and best of luck with your research.

    I live in a section of the country that has very few people afflicted with the virus, compared to surrounding counties and states, and so I count myself lucky to live in an isolated part of the U.S. that is relatively off the beaten path. The largest cities are 35 and 40 miles away, but I don't normally go to these cities except for doctors' appointments, which have all been cancelled anyway. I had been assisting a lot of people with their Irish genealogy before the plague struck, and continue to do so, and so for me not a lot has changed. But I can't wait for this thing to end because too many people have suffered for the past two months.

    From what I understand many of the New York City suburbs have been hit hard by the virus, especially New Rochelle.

    Thank you for writing Pamela, and once again, good luck with your research.
