Historical Birth Records

The King County Archives holds the following historical birth records. 
  • Birth Registers - Seattle only (1890-1907)
    These records are organized chronologically. Records from 1890-1891 have self contained indexes. Records from 1891-1907 have no included indexes. All of these records can be accessed using the Birth Indexes (below). Entries from 1890-1891 include date of birth, sex of the child, name and birthplace of both parents, residence of the parents, attending physician and remarks. Entries from 1891-1907 include name of the child, date of birth, place of birth, sex, race, whether a live or stillbirth, the name, age, race and birthplace of both parents, as well as the occupation of the father and number of births of the mother. These records are digital images. Identical digital copies and microfilm records are also at the Puget Sound Regional Branch of the Washington State Archives (external link).
  • Birth Registers - County wide (1891-1907)
    These records are organized by first letter of the last name, and then chronologically. They contain the same information as the Seattle Birth Registers (above). These records are digital images. Identical digital copies and microfilm records are at the Puget Sound Regional Branch of the Washington State Archives (external link).
  • Birth Certificates – Southeast King County only (1913-1951)
    These certificates are limited to districts in southeast King County, in districts containing Black Diamond and Enumclaw. The records are organized by district and then chronologically.
  • King County Birth Indexes (1890-1952, 1954-1966)
    These alphabetical index entries contain individual’s name, birth date, mother’s maiden name (surname only) and birth certificate number.
