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.
There are online passport document collections available, both free and via subscription.
