I have a question about apostrophes showing possession. If a name ends in s, such as Thomas, you do not add an s. But is that true with names that end with z or x? Inez' or Inez's Alex' or Alex's?

I find it quaint my dear, to find you all alone
With the TV off, not talking on the phone
The tears that streak you face, tell me you're so blue
Please, dear, understand, I always will love you

Tonight you do not understand, why I had to go
Some thing just have to be, why, I do not know
I guess it was just my time, I heard him call my name
I had no choice, I had to go, when I heard death call my name...
