My suggestions, not in any particular order:
Yama - Means "twin" in Sanskrit. This is the name of the Hindu god of death. He is also regarded as the first mortal being, or in other words, the first person to die. This name is related to Persian Jam.
Yewubdar - Means "beautiful beyond limits" from Amharic ውብ (wb) meaning "beautiful" and ዳር (dar) meaning "limit, horizon, frontier, shore".
Yaw - Means "born on Thursday" in Akan.
Or maybe: What was the name of Jesus? Yeshua, Yashua, or Y'shua? Yashua is not an undisputed form, but due to the absence of Hebrew vowels is variously rendered Yeshua or Y'shua or Yahshua.
