If the question is about Traveller:
The iron gray horse was born in 1857 in Greenbrier County, which is now in West Virginia. He was first called Jeff Davis by Andrew Johnston, who raised him. He was renamed Greenbrier by his next owner, Captain Joseph M. Broun. Lee bought the horse from Capt. Broun for $200 during his late 1861 stay in South Carolina. Lee renamed his new mount Traveller.
Lee had two horses in his stable when he bought Traveller:
Richmond and Brown-Roan (“The Roan”)
