The letter Y represents a Yeoman.

The Yeomen Warders of Her Majesty's Royal Palace and Fortress the Tower of London, and Members of the Sovereign's Body Guard of the Yeoman Guard Extraordinary, popularly known as the Beefeaters, are ceremonial guardians of the Tower of London. In principle they are responsible for looking after any prisoners in the Tower and safeguarding the British crown jewels; they have also conducted guided tours since the Victorian era.

As of 2011, there were 37 Yeoman Warders and one chief warder and in 2007, Moira Cameron became the first women to ever hold the position of Yeoman Warder of the Tower of London after a 22-year career in the British Army. And in 2009 members of the British Navy were allowed to be a Yeomen Warder for the first time.
