This page provides you with information on how to find vital statistic information for American citizens.
"Vital records most commonly refer to records such as birth and death certificates, marriage licenses and divorce decrees, wills and the like. These records are created and held by local authorities (state and municipal/county), with possible exceptions for events overseas, in the military, or in the District of Columbia. They are not considered Federal records; therefore they are not held by NARA (National Archives and Records Administration)".
