MacGorman, also known as McGorman, Gorman, or O'Gorman, is an Irish Gaelic clan based most prominently in what is today County Clare. The paternal ancestors of the clan are of the Laigin and emerged in what is today County Waterford. As leaders of the Uí Bairrche, they competed with the Uí Cheinnselaig in the 5th century for the Kingship of Leinster, ultimately losing out in that specific arena, but holding on to significant lands in the Leinster area.
