Carlyle St. Clair III

 is person living in the Mojave Wasteland in 2281.

Appearances
appears in Fallout: New Vegas. You need to find him in order to [SPOILER ALERT!] use him as an acceptable replacement for Ted Gunderson in the mission Beyond the Beef, if you chose to take the path of saving Ted Gunderson. Carlyle St. Clair is said to live north of The Strip. I have not been able to find him so if someone knows, please edit this.
