Cassidy Clan Chieftains

The Cassidy Clan is headed by the Chief of the Clan, who is referred to or addressed by the title “An O’ Caisideach,” and the officers of the Executive Committee. The An O’Caisideach is an honoree position and ex-officio member of the Executive Committee.

The first An O’ Caisideach was Sean Ó Caiside of the Republic of Ireland, who was designated honorary Chief of the Clan for life. Sean served in this position from 1991 to 2003. With Sean’s passing, his wife Noirin Caiside was designated Chief of the Clan and served as Chief until 2005

Dr. Sheila Cassidy from Australia was inaugurated as An Caisideach inaugurated on Devenish Island at the 2005 Cassidy Clan Rally.

Three years later Philip Patrick Cassidy (known as Pat) from County Fermanagh was installed as An Caisideach, and served as our Chieftain through the 2014 rally. He passed away in August 2014.

  1. Hi! I just came across your site while investigating my husband’s ancestry. How wonderful to have such a great resource!
    We live in Pittsburgh Pennsylvania but have plans to visit Ireland. We’d love to try and visit during the next rally which, I believe, is going to be in 2017. Just wondering if you have an actual date set for this event. We’d love to join you! Please let me know. Thank you!

          1. My Friend, John Cassidy is coming with me to Ireland in September of 2017. He is most interested in finding out his roots and ancestry history. Can you recommend a good place to start his research?

  10. Have just joined the clan membership!
    Although I was born in Scotland, three of my (now deceased) grandparents were Irish and I am, therefore, applying for Irish citizenship. I’d love to hear from others who are doing the same.

  11. Following on from my former post. A little about my late Grandfather.
    Killed in action in France in July 1917, fighting as part of the Northumberland Fusiliers. He was 25 years of age when he was killed, and lived with his parents James and Bridget Cassidy at Rohan, Dunkineely, Donegal, before moving to Glasgow with his young wife, Martha (nee) McKenna, my late grandmother, around 1916. He joined the army to provide an income for his wife. At the time of his marriage, he changed his two Christian names around from “Patrick John” Cassidy to “John Patrick” Cassidy, so his army records record him as “John Patrick” even though he was named Patrick John at birth. I hope this doesn’t cause too many issues when I apply for Irish citizenship. I’m currently trying to get hold of his birth certificate and his death certificate.

  12. I am Jules McCue from Wollongong Australia.
    My great great grandmother was Mary Cassidy from Draperstown ( Ballinascreen) Derry. She left there via Belfast and Portsmoith to Sydney on the Thetis ship in 1848.
    I believe I have located her family from the townland of Cahore which at the top is part of the town near the cross of above town. There were blacksmiths there on Patrick Street througgout the 19th century into twentieth. On her death certificate says father James Cassidy a blacksmith. There is a Nicholas Cassidy who marries at Draperstown ( Ballinascreen), to Isabella McGurk and some children baptised there before moving to Maghera. Others sibblings are Catherine, Patrick and John.

    Also, elizabeth McKlosker did marry Francis Cassidy from Moneyneany another townland close by at Ballinascreen parish. The RCs were being pushed out of town and possible Mary Cassidy’s parents dued in the workhouse. Why else would she come all the way to Australia alone at 20 years of age?
    She married Peter Crean/ Crane and lived all her life at Wellingtin NSW having 7 children.

  13. My ancestors (Simon Casady n Eleanor Layton) came from Co. Fermanagh, Ireland to Virginia. I wanted to know who are their ancestors n any other family. My name is Stacey L. Casady McNamar.
