A few links for this most splendid o' days.
Roger Mansell (1935 - 2010)
This is my dad's memorial website, which tells about his fascinating (if gruesome) research and the splendid archive he donated to Stanford University's Hoover Institution just last year. He always celebrated St Patrick's Day with a bodacious party. I'm sure he is partying on!
Michael Hogan on the Irish Soldiers of Mexico
The link is to Hogan's guest-blog post about his books on the little-known "San Patricios."
The Life and Work of William Butler Yeats
The National Library of Ireland's website.
The Leprechaun webcam
In Tipperary (where else?)
