Early life [change]
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. 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 Yoshiie, who was a famous ancestor. He received permission from the emperor to change his family name from Matsudaira to Tokugawa.
