A statement from Guardian.co.uk.
We apologise to the staff and pupils of Kilkenny College, a boarding school in south-east Ireland, for mistakenly identifying it as a school that Saoirse Ronan left because teachers and students were giving her a hard time (A name to reckon with, 23 January, page 16, Weekend). Contrary to what we stated, Saoirse Ronan was never a student at Kilkenny College. We accept that Kilkenny College guards the interests of its pupils and regret any implication to the contrary.

I think you better let Kilkenny college realize this is just Saoirse fans site and not her official site and that the apology was from the people who wrote the Guardian and not Saoirse herself, because they took it upon themselves to say in the Kilkennly news to say that they received an apology from Saoirse from this site. That’s not true at all, You guys just posted the artcile and this is not Saoirse official site.
