Well, maybe. I'd need more info about dates, etc. There was a Dorothy Reese (born 6 April 1916) who married William Cody Garlow born 1913, son of Irma Louise Cody Garlow, daughter of Buffalo Bill. Thus, Dorothy's husband was Buffalo Bill's grandson. However, I don't believe William Garlow took the name Kit Carson. Their son Bruce, however, did. Bruce adopted the name Kit Carson Cody and I believe he currently lives in Cody, Wyoming. He is deeply involved in the Cody Family Association (which is having their annual family gathering in Cody June 28 - July 1. Contact their website for info if you want to attend). They did not have a son Kevin. They did have sons John, Bruce and Barry. If you are absolutely certain your Dorothy Reese married Kit Carson and/or positive they had a son named Kevin, this is NOT the right Cody family.
