Kensington Regiment (Princess Louise's)

41 (Princess Louise's Kensington) Signal Squadron (Volunteers) can trace back its history over 199 years to 1798 when the Corps of the Kensington Volunteer Association was enrolled in answer to the threat from France. The squadron's motto "Quid Nobis Ardui" meaning "Nothing is too hard for us." In 1908 Her Royal Highness the Princess Louise, Duchess of Argyll consented to the use of her name by the Regiment and thereafter became known as Princess Louise's Kensingtons.

Now the 38 (City of Sheffield) Signal Regiment - more information on the Wikipedia page
