*Begay is a surname of Navajo origin, representing the expression biyeʼ, “his son.”* The expression could follow a father's name within a longer personal designation. Its later treatment as a fixed surname reflects the recording of Navajo names in an American English naming system. It does not identify one ancestral father shared by everyone named Begay. See the Begay entry in the Dictionary of American Family Names.
The Navajo Meaning Behind Begay
The Dictionary of American Family Names, second edition, gives biyeʼ and the alternative form bigheʼ as the source of Begay. The meaning concerns a relationship to another person; it is not an occupation or a place name. The dictionary explains that non-Navajo recorders could mistake this element of a longer name for a surname. Read the dictionary explanation.
Begay is therefore an adaptation of the Navajo expression into an English written form, rather than an English translation of its meaning. Preserve that distinction when recording an ancestor's names: the original expression, its written approximation, and a translated explanation are different pieces of information.
How a Relationship Term Became Hereditary
Theodore Holland Jr.'s study of Navajo naming, based on fieldwork begun in Arizona in 1991, describes how schools, census taking, traders, and other institutions encouraged names that fitted English administrative expectations. He gives Begay as an example of a teacher approximating the sound of the final element in a Navajo name and treating that element as a last name. Some interviewees traced their inherited English names to a grandparent's school naming. See Holland, 1995, pp. 282–283.
This documents a process, not a single event that created every Begay family. A relationship expression could be applied to different people, so the shared etymology cannot establish a shared founder. For your own line, distinguish the earliest record of the spelling from evidence that children subsequently inherited it. Parent–child links across dated records are what establish that transition.
Holland also distinguishes sound-based adaptations from translated names and unrelated English names assigned to individuals. His examples show why searching only an assumed equivalent can miss a person's earlier identity. See the three naming routes on p. 283.
Begaye and Other Names Worth Comparing
Begaye is an attested variant of Begay. The earlier Dictionary of American Family Names, reproduced by FamilySearch, explicitly identifies that relationship. Include both spellings in a search, while checking whether the records concern the same person or connected generations. See the Begaye dictionary entry.
The Navajo forms biyeʼ and bigheʼ above are linguistic source forms; their appearance in an etymology does not establish that an ancestor used either as a fixed written surname. Likewise, a name with a similar relationship meaning is not automatically a spelling variant.
Smith offers a different comparison. Peter McClure's discussion of American surnames notes that Native Americans also adopted existing English surnames such as Smith. This helps explain why a family history may involve names whose languages differ. Smith is not a translation or variant of Begay, and a proposed change between them needs individual evidence. Read McClure's discussion. Our guide to testing related surname spellings explains how to assess a possible connection.
A Dated U.S. Frequency Figure
Writing for Oxford University Press in 2024, surname scholar Peter McClure reports 17,533 bearers of Begay in the 2010 U.S. census. This is a historical national figure, not a current worldwide total or a count of Navajo citizens. See McClure's article.
The Census Bureau describes its surname release as aggregate counts and characteristics, without identifying individuals. Consequently, surname frequency cannot establish a family relationship or locate a particular ancestor. See the 2010 surname data description.
Researching a Begay Family in Records
Begin with the person, household, and community you can document. A useful working file should preserve each complete name exactly as written, alongside the date, place, relatives, and source reference. Do not silently replace an unfamiliar name with Begay because its meaning seems compatible.
For a family associated with a Navajo reservation or agency, the National Archives' Indian Census Rolls, 1885–1940 are a useful starting point. Depending on the roll, they may give an Indigenous name, an English name, family relationships, age or birth date, and agency or reservation. Coverage and questions vary, and not every tribe or reservation appears for every year. Read the National Archives' census-roll guide.
- Choose the jurisdiction before searching broadly. The M595 inventory lists separate Eastern, Northern, Southern, and Western Navajo Reservation rolls for 1937, as well as Leupp. Match a family's documented location to the relevant heading; the surname alone cannot select it. Consult the M595 jurisdiction and date list, rolls 275–281.
- Compare the original image with the index. Search Begay and Begaye, then compare household members, ages, and location. A plausible spelling match with a different spouse or incompatible children needs further investigation.
- Follow the naming transition through relatives. If a parent and child have different recorded surnames, look for records explicitly describing their relationship. Where a family account connects a name change with schooling, use the school and attendance dates as leads for identifying the relevant surviving records.
- Keep a record of unsuccessful searches. Note the agency, years, spelling, and collection searched. Missing from one roll is a narrower finding than missing from all records, especially where coverage is incomplete.
The Dawes Rolls are not a general register of Native American people. They concern the Cherokee, Choctaw, Chickasaw, Creek, and Seminole Nations in Indian Territory, rather than serving as a Navajo census. Choose them only when the family's documented history points to those records. See the National Archives' explanation of Dawes records.
Use the surname evidence checklist to separate what a record states from what you infer. Begay's Navajo etymology supplies useful linguistic context; it does not by itself prove a reader's ethnicity, tribal citizenship, ancestral community, or relationship to another bearer. The Native American surname guide explains the scope of this broader collection.
