Liam & Aidan O'Donnell
Liam Thomas and Aidan Patrick O'Donnell (also credited as Liam & Thomas O'Donnell and Aidan & Matthew O'Donnell) are two American child actors. In July 2004, they began appearing as the fictional character "Ace Buchanan" on not only one, but two soap operas; All My Children and One Life to Live, as baby "Ace" was part of a storyline "so big it had to be told on two soaps". Since November, Liam and Aidan have only been appearing on All My Children, and their character has been renamed "Thaddeus James Martin". ABC Daytime has always credited the twins as Liam & Thomas O'Donnell.
