Gotta love Robbie's version. None better. One thing though. They were written on behalf of Bryan Hunt, not Byron. He died on 10 July 1892, at the ripe old age of 94. (Good on ya, Bryan!) His wife, Elizabeth ‘Eliza’ Hunt (nee Kelly) died in 1872, at age 73. There is a Wikipedia article about the song and it's also referenced on the County Mayo website, where the family tree is also documented.
