What's In A Name?

Isaiah 65:1 

I have been inquired of by those who asked not, I have been found by those who sought Me not, I have said, 'Behold Me, behold Me,' Unto a nation not calling in My name.

Gen 16:13 

And she called the name of the LORD that spake unto her, Thou God seest me: for she said, Have I also here looked after him that seeth me?

The  word/title "LORD" translated in most translations in Hebrew is actually His proper name, YHVH, which occurs over 6,800 x's in the Hebrew scriptures! 

If it wasnt important to know, why was it written so many times, and why was it removed from most bibles but the Hebrew one? Almost as if the "chosen ones" were trying to keep His proper name hidden from the non-Hebrew speaking/understanding masses?

(In much the same way if voting wasnt important, why do republicans go through extreme lengths to make it harder and next to impossible for people of color to vote?)

If His name, YHVH, was THAT important to be given over 6800x's in the Old Testament, WHY ISNT EVEN THE LATINIZED VERSION OF HIS NAME MENTIONED ONCE IN THE NEW TESTAMENT??

If people resent when their proper names arent used and mispronounced properly how much more so our Creator? 

I have to also state, it was customary for Jews to speak and write His name as it is given in scripture. During the life and times of Christ, He and the disciples would have saod and written YHVH. Why do we believe they would have used anything other than HIS proper name no matter what language they were writting? 

How would the Romans, Greeks, Egyptians, etc, differentiated their many gods from the God of the Jews?
