SALT LAKE CITY — is offering free use of a database with 60 million records on U.S. servicemen of World War II to mark the Dec. 7 anniversary of the Pearl Harbor attack.

The Provo, Utah, company says one in five Americans is a direct descendant of a World War II veteran.

One notable database opened for viewing are Navy muster rolls, which consist of more than 33 million records detailing nearly all of the enlisted personnel who served aboard a Navy ship from 1939 to 1949.

Those rolls list the 2,402 servicemen killed in the surprise attack by hundreds of Japanese fighter planes.

The company's entire World War II collection will be open until Wednesday.
