More than 200,000 Titanic-related records have gone online to mark the 100th anniversary of the ship's sinking.

The records have been gathered by family history website Ancestry.co.uk and include lists of the dead and information about survivors.

Those logging on can read the wills of the Titanic's captain, Edward Smith, as well as those of American tycoons Benjamin Guggenheim and John Jacob Astor.

All three were among the 1,500 passengers who died.

Other records now online include images of grave headstones of 121 Titanic passengers, more than 329 coroner inquest files, and records of 330 bodies that were recovered at sea.

The new website also has a passenger list from the vessel Carpathia, whose crew bravely battled through the ice-strewn Atlantic to rescue more than 700 survivors.

The collection is free to view until May 31.
