Burmese names

Friends,

I hope some Myanmarese (Burmese) viewer could help me here about
Burmese names. As I do not have the Library of Congress guide to
book classification rules and guidelines, I am trying to figure out
how to index Burmese name like

SHWE ZAN AUNG

(1) Do I enter the name as it is, as it is a unique name?
(2) Or, is the surname AUNG, so that I should index it so.

I notice most biblios index the name under AUNG, though I have a
feeling it should be SHWE.
