I am a Keogh from the Waikato in NZ living in Hong Kong. I am a descendant of John Keogh and Mary Noonan. Here is an excerpt of the information that I have.
John Keogh was born in Kilnoe (today known as Bodyke Parish) in County Clare near Limerick city about 1830. According to John’s death certificate his father was James Keogh and his mother’s maiden surname was Martin.
I visited Bodyke Parish in 2004 and didn't have any luck tracking down the Keogh family but saw the Noonan family in the graveyard there. It makes me wonder if our information is correct. Many people I have met since who are from Clare have said that Keogh isn't a Clare name.
I will be visiting Ireland again in August this year (2012) so would love to find some leads and trace back my heritage. I guess too, it would be useful to find the connections with the Keogh clan back in NZ.
