based on the main article, 'Jehovah'
Jehovah's Witnesses say that Jehovah is the correct and original pronounciation of God's name. However according to the historical records they are wrong. What if God prefers to be called, 'I AM' or YHWH some other name instead of Jehovah? Exodus 3:13,14
The God of Israel YHWH (Hebrew: יְהֹוָה) is referred to in the Hebrew Bible. The name YHWH is a combination of the future, present, and past tense of the verb "howa" (Hebrew: הוה) meaning "to be" and translated literally means "The self-existent One".
A further explanation of the name was given to Moses when YHWH stated Eheye Asher Eheye (Hebrew: אהיה אשר אהיה) "I Am that I Am". The name relates to the true essence of God, which transcends individuality to include all things and the entire universe. It also represents God's compassion towards the world in that He encompasses all things. He is 'omni present' and therefore by definition must reside in all living and non living things. 
1. The name of God in Judaism used most often in the Hebrew Bible is the four-letter name יהוה (YHWH), also known as the Tetragrammaton. El, Elohim, El Shaddai, Adonai, Elyon, and Avinu are regarded by some Jews not as names, but as titles highlighting different aspects of YHWH and the various 'roles' of God. See Names and Titles of God in Judaism (Wikipedia) for a more in depth explanation of the following names and titles of God.
