For a short Chinese surname connected to Williams, begin with 威 Wēi, 韦 Wéi and 卫 Wèi. All three are real surnames. They share the spelling “Wei” when tone marks are removed, but they offer different connections: 威 retains the opening of a Chinese transliteration, 韦 changes the character and tone, and 卫 adds a defensible link to protection.
That is a choice for a Chinese name, rather than an official conversion of your family identity. If you already use a Chinese surname, there is no reason to replace it simply to make it resemble Williams. If you need people to recognise the original English surname, keeping its fuller transliteration may serve you better.
Start with the sound you are preserving
Williams is pronounced with initial stress, commonly /ˈwɪli.əmz/ or /ˈwɪljəmz/. Chinese 威廉斯, Wēiliánsī, represents it with Mandarin syllables; 威廉姆斯 is another recorded form. Neither reproduces every English sound. Extracting 威 keeps the opening of that transliteration and drops the rest; it does not make Mandarin wēi identical to English /wɪ/. English pronunciation, Chinese transliteration entry.
This distinction matters when you explain the name. “I chose the first character of a Chinese rendering of Williams” is accurate for 威. “Williams means Wei” would not be. You can keep Williams in an English signature and use your chosen Chinese full name in conversation without pretending that one is a word-for-word translation.
威 Wēi: the most direct first-character choice
威 is not merely a convenient transliteration character. The dictionary explicitly records it as a surname. Its ordinary meanings include authority and dignity, alongside stronger senses involving power. 威 dictionary entry.
This makes 威 the first option to compare if continuity with 威廉斯 matters most. It preserves both the written opening and its first tone. The stronger everyday associations may appeal if you like a firm introduction; they may feel too emphatic if you want something understated. That is a preference, not evidence that the surname is unsuitable.
A real surname need not be familiar to every listener. Be prepared to identify it with “威严的威.” This is a spelling cue, not a claim that dignity defines your personality. Choose the given name afterward, so the complete combination is judged as a personal name rather than as a slogan about power.
韦 Wéi: a nearby sound with a different character
韦, traditional 韋, is another documented surname. Compared with 威, it keeps the Mandarin syllable's consonant and vowel sequence but changes the first tone to a rising second tone. It is a substitution near the opening of the transliteration, not a character extracted from 威廉斯. The character also has a lexical sense connected with processed hide or leather; that does not establish an occupation for every 韦 family. 韦 dictionary entry.
Consider 韦 if the connection you want is mainly audible and you prefer a character without 威's overt forcefulness. You give up exact written continuity with the transliteration. Without tone marks both become “Wei,” so keeping the Chinese character visible is useful when recording or sharing the name.
卫 Wèi: sound plus a limited meaning connection
Williams is a form related to William, with an ending that can be genitival or a later addition; a blanket “son of William” explanation is too narrow. It is also well established in Wales. The older Germanic elements behind William concern will or desire and a helmet or protection. These are name-history facts, not a description of each modern family. Williams history, William history.
卫, traditional 衛, is a real surname whose ordinary meanings include guarding or protecting. It therefore offers a connection to the protective element, while keeping a nearby wei sound with a falling fourth tone. This is a partial semantic bridge: 卫 does not encode the whole history of Williams or translate its ending. 卫 dictionary entry.
Choose it if protection is the part of that older name story you want to carry forward. Do not add a famous warrior simply to make the choice sound grander. A specific Chinese defender would introduce a separate personal association, and the evidence here does not make Williams a shared clan name or a military occupation.
Try the full name before deciding
Keep the given name constant during an initial sound comparison. For example, 威明 Wēi Míng, 韦明 Wéi Míng and 卫明 Wèi Míng show how changing only the surname changes the rhythm. These are listening examples, not three finished recommendations. 卫明 is pronounced like 未明, “not yet clear,” which shows why individually positive characters still need a whole-name check.
Start with 威 when the transliteration is your anchor, 韦 when you want a nearby sound with a different character, and 卫 when the protection connection matters. Say your preferred pairing in a normal introduction, ask what someone heard, and explain the characters afterward. That small test reveals more than choosing a surname from unmarked “Wei” alone.
