One of the many – and often overlooked genealogy documents for us to research are passport applications and the passports themselves.

For United States passport applications, the required reading is from the U.S. National Archives – Passport Applications. The history, types, limitations, and how to access the microfilms of registers and indexes are included.

So what unique and interesting information can be found in a U.S. passport application from the collection of 1795 – 1925?

  • Name of applicant
  • Birth date or age
  • Birthplace
  • Date of application or issuance of passport
  • Marital status
  • Father’s or husband’s name
  • Father’s or husband’s birth date or age
  • Father’s or husband’s birthplace
  • Father’s or husband’s residence
  • Wife’s name
  • Date of immigration
  • Date of naturalization and where and what court
  • Ship information
  • Possible information about children and other relatives
  • Occupation
  • Current residence and length of residency
  • Destination and reason for travel
  • Physical description – with no photograph, this may be the only hint of what they looked like
  • Photograph – this is a huge bonus as these applications provided the only photograph that I have of some ancestors. Low quality, but better than nothing.
