This service relies on data provided by INSEE but is not affiliated with the institution.
In order to search for a record you must enter at least one surname. The other fields may help you refine the results but are not required.
The order in which you specify the names does not matter. Only the records that match the names are returned (but these records can contain other names that you did not include).
You may also select a location (town, department, region or country), in this case all the records that occurred at this location will be returned. The old town names are written in parenthesis, followed by the current town name.
Dates and sorting
Finally it is also possible to search with a specific date or a time interval (open or closed). The data will be be sorted according to the dates of the specified event kind.
This database relies on the data provided by INSEE, it may contain missing or erroneous entries. Please do not report errors in the data.
The accentuation of the given names is not necessarily correct.
Some locations could not be collected and are thus not displayed.
The service may also be used through the mean of its API, which is described here.
The root domain is the following: https://insee.arbre.app
The results are returned in json format.
Authentication is not needed; access is free and does not require a token.
For the good operation of the services you are asked to avoid abusing the API: please try to stay below 3600 requests per hour and per ip address.
You are also encouraged to use an explicit User-Agent field (even if this is not mandatory).
