The original arms are described as follows:
‘Sable three bucks’ heads caboshed argent attired or, Crest a serpent nowed proper’
- Motto ‘Cavendo Tutus’.
The Hartington Lodge Banner displays the ‘Sable three bucks’ heads caboshed (the
head is represented affonte and removed behind the ears so that no part of
the neck is visible).
Those arms were borne by Sir William
Cavendish, second husband of Bess of Hardwick, and by her second son, Sir
William Cavendish, created Baron Cavendish in 1605 and Earl of Devonshire in
1618.
The fourth Earl was raised to Dukedom in
1694 whereupon the arms were added to as
follows:
‘Supporters on either side, a buck proper wreathed about the neck with a
chaplet of roses alternately argent and azure’.
