[3] The basic pattern of the arms was based on those of the Osborne family of Kiveton: quarterly ermine and azure overall a cross Or.
Thomas Osborne was created Earl of Danby in 1674, Marquess of Carmarthen in 1689 and Duke of Leeds in 1694.
This refers to the fact that The Earl of Danby was one of the "immortal seven" who signed the Invitation to William at the Cock and Pynot Inn in 1688.
The crest was intended to depict Thorpe Salvin Hall, some time seat of the Osbornes.
