The short story
Do in American records is most often the Vietnamese surname Đỗ, written without diacritics. Đỗ is the Vietnamese form of the Chinese surname 杜 (Mandarin Du), a major East Asian clan name whose Chinese history is habitational and clan-based rather than a transparent everyday word in Vietnamese. DAFN also lists Vietnamese Đồ from Chinese 涂/塗 (Tu), Chinese romanizations of 杜 and 卓, and Korean To. Those separate streams can all appear as Do after immigration and romanization. Place fits the leading Chinese–Vietnamese clan tradition, but the several look-alike origins keep confidence disputed.
