O’Keeffe Clan – One Name Study & Family Tree

Welcome to the O’Keeffe Clan Website!

In 1996, during the early days of the internet, the O’Keeffe Clan web site was created to help descendants of O’Keeffe, and other spelling variations, connect and share information with one another.  Over 25 years later, and with the advent of new technology, our focus has expanded to the preservation of genealogical, historical, and biographical data pertaining to the O’Keeffe surname. 

This One Name Study is funded and supported by members – no ads.


O’Keeffe Clan Family Tree:

A One Name Study – O’Keeffe – centered family tree. Originally built from information provided by O’Keeffe researchers, Message Boards, and Genealogy Forums, the database now includes many publicly available O’Keeffe records.  Sources include but not limited to:  Census of Ireland, Irish Genealogy, RIP.ie, Irish Army Census Records, Find a Grave, WikiTree, and Family Search. Currently there are over 160,000 O’Keeffe’s and their spouses in the combined on-line databases.

2016 O’Keeffe Clan Gathering:

The Diaspora is an Irish project to promote tourism in Ireland to help with their economic situation.  The idea is for the local people in Ireland to collectively use parish records and search for descendants of those who left Ireland.  One of the branches of project became known as the Irish Gathering.  

In 2016 an O’Keeffe Gathering was held in Ireland.  The website for the project, “okeeffeclans.com”, has since retired; the valuable contents of the website have been preserved here.  You may still visit the Facebook page “O’Keeffe clan rally 2016”.
