Quach
A Vietnamese surname, usually understood as a modern romanization of a Chinese-derived family name used in southern Vietnam.
The #3,598 most common surname in the United States (2010 Census) — about 1 in every 31,205 Americans shares it.
Etymology
Quach is a Vietnamese surname associated with the Sino-Vietnamese reading of a Chinese family name usually written 郭. In Chinese the character traditionally refers to an outer city wall or a protective rampart, and as a surname it is well established in East Asia. The Vietnamese form Quach reflects Vietnamese spelling and pronunciation of that inherited name.
History
The surname is found in Vietnam and in overseas Vietnamese communities, especially through modern migration. Like many Vietnamese surnames, it ultimately entered the language through long historical contact with Chinese writing and administration. In diaspora settings it is often written Quach without diacritics, which is also the usual form in English-language records.

Fun fact
In Romanized Vietnamese, diacritics are often dropped in everyday records, so Quach may correspond to the tonal spelling Quách in Vietnamese contexts.
