Early life
At birth, his name was Matsudaira Takechiyo.  

In 1562, he changed his name to Matsudaira Motoyasu. The second syllable -- -yasu -- comes from the name of his grandfather Kiyoyasu.Sadler, Arthur Lindsay. (2010).  The Maker of Modern Japan: The Life of Tokugawa Ieyasu, p. 51.  A few months later, he changed his first name to the one by which he is known today.  The first syllable --  Ie-'' -- comes from the last part of the name of Minamoto Yoshile, who was a famous ancestor.Sadler,  p. 70.  He received permission from the emperor to change his family name from Matsudaira to Tokugawa.Janse, Marius B. (2002). The Making of Modern Japan, p. 29.
