Silver Cloak
From Tardis Wiki, the free Doctor Who reference
The Silver Cloak was a group of old pensioners that was set up for the purpose of finding the Doctor. The group was created by Wilfred Mott, who believed the Doctor could help his granddaughter Donna Noble remember him. The group eventually found the Doctor within two hours of their search, taking a picture with him and then leaving for Wilf to speak to him. (DW: The End of Time)
