The hunt is on for the owners of two passports held by a husband and wife - born more than 110 years ago.

The passports were found alongside a key in Staines Park by a member of the public who handed them into Surrey Police.

They belonged to Dorothy Hickman, who was born in Stoke Newington, London in 1911, and her husband Mark Hickman, born in Greenwich, London in 1912.

According to Surrey Police, the couple had a son called David, who was born in 1940.

The force hopes that they can return the passports to a family member.

In a post on Facebook, Surrey's Spelthorne Beat said they would typically hand all "normal" passports back to the Passport Office to be cancelled.

However, they believe these passports could have "sentimental value" - and so have turned to the "powers" of social media to track the owner down.

The force said: "We are using the powers of social media to hopefully find the owners or family members of some lost property.

"A member of the public has handed in two passports and a key found in Staines Park on July 28.

"If they were normal passports we would be sending these back to the Passport Office to be cancelled.

"BUT. These are very old passports - a husband and wife born in 1911 and 1912.

"We believe they may be of sentimental value to someone and would love to get them back to their home."

The force have asked the owner of the passports to go to the front counter at Staines Police Station.

They also urged other members of the public to share the post so that the owner can be tracked down.

Until August 1988, the particulars of a wife or husband could be included in the UK passport if both partners were British citizens.
