The Black and Tan is believed to descend form hunting dogs imported to America by Robert Brooke in 1650.  These hunting dogs were the ancestors of several varieties of American hounds and stayed with the Brooke family for more than 300 years.  Afterwards French Foxhounds were bred in after George Washington received them as gifts from the Marquis de Lafayette.  Much later, the breed's speed and stamina were improved introducing Irish Foxhounds.
