Ah lahk it!
Anneza is just
Anne (my middle name) plus ZA, which is our international code - web addresses are .co.za, international car licence plates are ZA. Goes back to the merry days when our official languages were English and Dutch. Just a useful handle that even I can't forget ...
Anna - Afrikaans form - can have 2 diminutive forms in Afrikaans:
Annie (sounds like Unnie) or Annetjie (sort-of Unnuhkey). (And
Pavlos would look like
Paul and sound like Pole.)
