For Adams, compare 亚 Yà (traditional 亞) with 安 Ān. 亚 retains the opening character of 亚当斯 Yàdāngsī and has a separately documented surname reading; 安 gives you a different character, a level tone and an n ending. Decide by the connection you want to keep and the complete Chinese name you will use. 1, 2, 3
I would start with 亚 if retaining that visible connection matters most. I would compare 安 if its pronunciation and the final Chinese name appeal to you more. Keeping 亚当斯 in full remains the clearest option when the purpose is to represent your existing surname rather than shorten it for a Chinese-style name.
What 亚当斯 preserves
English Adams is commonly pronounced approximately /ˈædəmz/: the first syllable is stressed, and the final consonant is normally z-like rather than s-like. Chinese-language institutional usage provides clear examples of 亚当斯. Tsinghua University's account of Harrison Adams gives the English name alongside that Chinese spelling. The example establishes a real transliteration; it does not suggest a relationship between the reader and the person named. 1
In Mandarin, Yà-dāng-sī has three syllables, with fourth, first and first tones. It adapts the English vowel and consonant sequence to Chinese syllables. Yà introduces a y-like glide, dāng has a nasal ending different from English -dam-, and sī is an extra syllable rather than the English final /z/. These are normal kinds of compromise in transliteration, not grounds for pretending the two pronunciations are identical.
If you keep only 亚, almost all the surname's internal structure disappears: the d, the following vowel, the m and the final z no longer have their own representation. The retained link is especially clear on the page because 亚 is the first character of 亚当斯. It is much less recoverable from hearing Yà alone. Keep Adams in a bilingual display whenever identification across languages matters.
Check the rare surname rather than dismiss it
The entry for 亞 distinguishes several readings. Its surname sense appears under yà, not under yā or è. This provides surname-specific support for the reading used here. The simplified form is 亚. The historical quotation attached to the surname entry establishes lexicographical attestation; it does not verify the genealogy of a present-day Adams or of every Chinese family using the character. 2
亚 has other dictionary meanings, including being next in order or secondary, and it is used in the word for Asia. Those meanings are not a verdict on a person carrying the surname. You do not become “second-best,” and your surname does not assert Asian ancestry. In a personal name, its role here is a documented surname selected for its written continuity with Adams.
A less familiar surname can require an extra sentence when introducing yourself. You could say 我姓亚，亚当斯的亚: “My surname is Yà, the 亚 in 亚当斯.” It is reasonable to decide you do not want that explanation every time. It is equally reasonable to prefer an unusual but well-supported surname. Familiarity is a practical consideration, not proof that one character is legitimate and another is not. This article makes no population estimate for 亚.
安 Ān is a different adaptation
安 Ān is independently listed as a surname under the first-tone reading ān. Its meanings include being settled or at peace. Those meanings can be personally attractive, but they do not translate Adams or establish what your ancestors valued. 3
The sound changes are concrete. Compared with Yà, Ān drops the initial glide, adds a final n and changes a falling tone to a level tone. Compared with English Adams, it keeps only a broad vowel-based opening and introduces a nasal in a different place. Mandarin an should not be presented as an exact equivalent of English /æd/. It also gives up the literal first-character match with 亚当斯.
Why consider it at all? You may prefer how Ān joins your chosen given name, or find it easier to explain by saying 安全的安, “the 安 in ānquán, safety.” That is a sound-and-usage decision you can test directly. It is not a reason to replace 亚 automatically, and it does not turn “peace” into the historical meaning of Adams.
Adams carries a personal-name history
The Dictionary of American Family Names identifies Adams in English, Dutch and northwestern German contexts as a patronymic formed from Adam. It also records Irish and Scottish routes and the absorption of related surnames in North America. That supports a personal-name relationship at the level of surname history; it does not identify the particular Adam in a reader's family. 4
For a Chinese name, this history supports treating Adams as a personal-name-derived surname. Neither 亚 nor 安 translates Adam; both are present-day adaptations with different sound and writing priorities.
A recommendation you can use
Choose 亚 Yà if the first character of 亚当斯 is the connection you want to retain. Choose 安 Ān if you prefer that distinct pronunciation and accept the weaker connection to the original spelling. Keep 亚当斯 Yàdāngsī if recognition of Adams matters more than brevity. None requires changing your legal surname or suggesting that your family belongs to a Chinese lineage.
Before settling on a full name, say the surname by itself, then together with the proposed given name. Test the actual tones, possible word combinations and how you would write it for someone who has only heard it. If your everyday Chinese environment uses a variety other than Mandarin, ask a speaker of that variety to check the complete name. This article's reading guidance is for Mandarin and does not substitute for that individual check.
The U.S. count and the separate British slot
In the recorded U.S. Census table, ADAMS ranks 43 with a published frequency of 413,470. The reference is the 2020 Census, released on 14 April 2026, and the standard surname frequency file has disclosure-avoidance processing. The number is not a count of 2026 residents and must not be replaced with a 2010 figure or a different file variant. 5, 5.1
That separate recorded row is Adams, website ordinal 70, in the private British Surnames list covering England, Scotland and Wales, not Northern Ireland. There is no reported count or verified modern reference year, underlying unit or counting method. It therefore remains a website ordinal with unresolved metadata, not an official current UK population rank. The two country notes must remain separate. 6, 6.1
Sources and evidence boundaries
The Tsinghua Adams example supplies Adams—亚当斯. 2. Hàndiǎn 亞, explicitly places the surname under yà; 3. MOE 安 independently establishes ān. 4. DAFN Adams via FamilySearch supports the personal-name origins, not the reader's genealogy.
The U.S. Census file and method report supply the separate recorded ADAMS rank 43, frequency 413,470: 2020 data released 14 April 2026 after disclosure-avoidance processing. 6. The British Surnames list and scope page supply Adams at website ordinal 70 for Great Britain, excluding Northern Ireland. The recorded GB row reports no count, and its reference period, counting unit and method remain unknown. It cannot be promoted to an official current UK-wide rank.
亚 preserves the transcription's first character while losing nearly all of Adams beyond the opening; 安 changes the character, tone and final consonant. Those trade-offs are editorial judgments, not measured acceptance. No religious or ancestral analogue is needed.
