She is from Myanmar. In addition to not having family names, people from Myanmar typically have names consisting of 2-4 words. Her name is 4 words. This causes additional issues as many people and systems assume that names are single words. Many web forms won't allow multiple words as first or last name. It's maddening.

I know Myanmar is one country where basically everyone has just one name, but there are probably others.
