Very weird - I went to post links to one of the current series on the seven signatories of the Proclamation of the Irish Republic, being shown on TG4, and it didn't post. Wonder why!

Anyway, in the Plunkett film, shown last Wednesday, his great-niece Honor O'Brolchain (who's working on a biography) makes the point that he was always called Joe.

Here are the links to this film, part of the Seachtar na Cásca series - the links won't work forever, so watch it now if you're going to.

Part 1
Part 2
