Oh thank you Gus! It's curious that a friend of mine who told me this, is named O'Gorman. Cool!

Thanks so much jenniej!!!

"Front/foremost of battle and last on it" which is assumed to mean "first on the battlefield and last (standing) on it.

Have you already found the meaning? I got with this site while searching. Though, I didn't hear about your question before. I hope it helps. http://www.irishgaelictranslator.com/translation/topic102621.html
