I am searching for the birth father of someone conceived in 1935. They didn't marry and everyone was long gone by 1940. Is there a way to search the 1940 census to find who all said they were living in a specific place in 1935?

    Hi Andrea, welcome. Please feel free to take a look at our tour and help center pages. In this question I'm assuming you are referring to the USA and will tag accordingly (it always helps to include place and date).

Yes, you can search the 1940 census for residence in 1935. Searching only for those who were in different places in 1935 and 1940 is not directly possible (unless you know the 1940 location), although scanning the search results will identify any 1940 residences that don't match the 1935 value.

At ancestry.com

ancestry has indexed "Inferred Residence in 1935" & "Residence in 1935"

At familysearch.org

familysearch calls the field "Last Place of Residence" (without specifying the year) on the individual's record page

You can also try searching from the general search pages, using the "residence" field at ancestry.com or the "any" life event field at familysearch.org, then filtering to drill down to the 1940 census. In addition to more steps, you are likely to have a lot of extra results, including those born in 1935 in that location (especially at familysearch).

In all cases, the results will include a lot of people who didn't move outside the city or county between 1935 and 1940.


  1. Non-urban areas are designated "Rural," or omitted, in the city field of the census page), so many placenames won't be specified in the 1935 residence field.
  2. Informants are identified in the census. The person(s) you are looking for may not have supplied the information for their household.
  3. Depending on the location, city and county directories may be a more direct way of searching.
