According to MacLysaght's book on Irish Family Names, Keena is a Westmeath name, but that is all the information given. I think I am a very distant relation to the John Keena mentioned, and all the Westmeath Keenas are said to have originated from the site of where my house now stands in a village called Ballymore, a few miles from Athlone. My fathers name is Patrick (also his fathers name). There is currently two families of Keenas living here. If anyone has any information on John Keena (I think he wrote a book on Keena family history, and father(/relative?) of Colm Keena, writer for the Irish Times) i would be greatful.
