I know this is a very old post, but I've recently discovered my ggf had a brother James. No idea if it's the same one, but he was born in 1869 in parish of Avoca, Wicklow. The townland is Ardanairy. Parents are Peter Canavan and Mary Carroll. My ggf came to Australia, he was Peter born 1862. Let me know if you think this could be the same family.
