(covers information from a vision or illusion)

Thomas Picard was one of Captain Jean-Luc Picard's sons during his Nexus experience in 2371.

In this experience, it was Christmas day, and Thomas and his brother and sisters enjoyed their gifts shortly before Elise Picard called for the large meal she has prepared. Thomas asked his father if he was scared when the children surprised him and later asked his father for help in building a castle. (Star Trek Generations)

Thomas Picard was played by Thomas Dekker. The script took the first name from the actor.
