Discover name origins with our advanced AI analysis
Analyze a first name, surname, or full name to determine a person's country of origin. This refers to the geographical, linguistic, and cultural roots of a person. In multicultural countries (e.g. the United States, Canada, France, South Africa, Australia, New Zealand), Name Diaspora may provide a more relevant classification.
When you use our name origin finder API or interface, you get key indicators. These help you find out where a name comes from. Here's what they mean:
Region & Sub-region of origin Estimates the broader geographic and cultural origins of the name.
Script (Latin, Cyrillic, etc.) Identifies the writing system used, helping determine linguistic and cultural roots.
Country of origin (ISO 3166-1 alpha-2) The most likely country associated with the name
Calibrated probability (Between 0% and 100%) Indicates the confidence level of the country of origin estimate. For instance, a 98% score means high certainty.
Alternative country of origin (ISO 3166-1 alpha-2) The second most likely country of origin.
Alt. Calibrated probability (Between 0% and 100%) Represents how likely it is that the name belongs to either the primary or alternative country of origin. The value is always greater than the standard probability. This is because it includes many different possibilities.
What is the origin of a name and how to find it?
A name origin refers to the geographical, cultural, and linguistic roots of a given name. It reflects the historical migration, ethnic background, and linguistic traditions associated with surnames and first names.
By analyzing names through onomastics, we can determine their likely origin. This process involves morphological and phonetic analysis, helping to trace names back to specific countries, regions, or linguistic groups.
By combining morphological, linguistic, and geographical insights, Namsor's name origin finder provides a very reliable estimation of where a name comes from.
Some first names and last names are often found in many countries in similar amounts. This makes their origin less distinct. In these cases, the calibrated probability might drop to 30%. This shows that the name could come from different origins. To provide a more comprehensive analysis, we return a list of the 10 most likely countries of origin for the given name.
How do we identify the country of origin from a name?
