Translation according to P. W. Joyce:
Knockatee in Cavan, Galway, Kerry, and Westmeath ; Cnoc-a'-tighe [-tee], hill of the (great) house, See Attee [reproduced below].
Attee, Atti, and Atty, at the beginning of names, represent in sound of Ait-tighe, the site of a house; ait, place or site, tigh [tee], a house. Attatee, same, only with the article a' added: site of the house. They are usually followed by another word, as in the following.
