We discussed United States Passport Applications in an earlier post. There is an article on the National Archives website about these applications, which are available on microfilm--unindexed.
These records are also:
- available at Ancestry.com as US Passport Applications and images 1795-1925--fee based--indexed.
- available at Fold3.com as Passport Applications, 1795-1905--fee based--indexed.
- available at FamilySearch for free (1795-1925)
The microfilm is available through the Family History Library (and on Archives.org) and may be in the collection of other large genealogical libraries. The microfilm is unindexed. Read the article on the National Archives site before using the microfilm or its digital images.
