In the DS9 episode 'Shadow Play' Dax and Odo encounter a village full of holographic people. They found it was created by a lone survivor of a Dominion attack who created the village and filled it with people that he remembered in his life. When the holoprojector started failing he wanted to let it die because the people were just memories of people he knew. But Dax convinced him that while the adults were just his memories come to life the children of those adults were original creations, outside his memories.

Wouldn't those holograms be sentient and thereby older than the Doctor? Was there any mention in books or comics what ever happened to the villagers?
