FamilySearch Indexing: US, WWI Draft Registration Cards, 1917-1918, Additional Helps
Q. How is Washington DC indexed? A. Washington is entered in the city field and District of Columbia is entered in the state field.
Q. Can an individual’s place of citizenship be used for birth country? A. The field helps tell us if the person was “native born (natural born)” it should be indexed as United States. However, if another country was listed as the country of citizenship, that should not be used as the country of birth. A person can be a citizen of a country other than his/her birth country.
