PROVO —  To mark the 100th anniversary of the sinking of the RMS Titanic, Ancestry.com is releasing thousands of Titanic-related records.

The records come from the ocean liner’s passenger lists, crew lists and lists of the more than 1,500 people who died at sea.

Also included are two databases from Canada. The first collection features headstone images of 121 Titanic victims buried at Fairview Cemetery in Halifax, Nova Scotia. The second, from the Nova Scotia Archives, includes 329 coroner inquest files and 330 records of bodies that were recovered by ships, along with the disposition of those bodies.

"As the years have passed, many generations have lost information that would confirm relatives who may have been aboard,” said Dan Jones, vice president of global content at Ancestry.com. “We're very pleased to offer these records free for a limited time and provide a single source to find answers to some long standing family mysteries."

The collection will be available at www.ancestry.com/titanic and can be accessed for free until April 15.

The RMS Titanic started its maiden voyage on April 10, 1912, with more than 2,200 people travelling from Southampton, England, toward New York. It sank on April 15 after colliding with an iceberg in the North Atlantic Ocean.
