There was an article in the Irish Times, March 10th, 2004 on efforts by Ringsend fishermen to have their right to net salmon on the Liffey. Two Ringsend families are mentioned in the article - and one is Pullen:
"Mr Turlough O'Donnell SC, for the 14 fishermen, said the tradition of salmon fishing in Ringsend was an extremely long one. In the case of one of his clients, Mr Anthony Pullen, his great, great grandfather had fished there as far back as 1830 and the fishermen concerned had a long tradition in salmon fishing." [IT, 10/03/04]
My father's family is from Ringsend, and I heard the name Pullen mentioned by old relations. The other family mentioned in the article is the Dents, another well known Ringsend family. One of the Dents - Bill Dent - was killed in a motorcycle accident in c1940s, age about 18. He was a first cousin of my grandmother (Kathleen Nealon).
