How does this Tokugawa relate to the Tokugawa restoration? Was this relating to a relative?

Do you mean the Meiji Restoration? I'm not familiar with a "Tokugawa restoration".
The Tokugawa clan dominated from the time of Tokugawa Ieyasu, after a period of struggle in the wake of Toyotomi Hideyoshi's death in 1598, till 1867, the time of Tokugawa Yoshinobu, when the shogunate was overthrown for good. As you probably know, the Meiji "restoration" 'restored' imperial rule and ushered in the Meiji era.
As far as I know, prior to Tokugawa Ieyasu, the clan was not significant and enjoyed more or less uninterrupted rule from Ieyasu to Yoshinobu.
