In the movie Tombstone.....

One of the Earp brothers was named Morgan.
A little off topic: When I was in high school I had a job washing pots and pans at the local hospital. A woman who also worked in the kitchen had the last name of Earp. Turned out that her grandpa? was one of the Earp brothers at the O.K. Corral. Wyatt Earp was her great uncle. She was a very interesting lady. When we were doing the dishes we would sing old time Western songs. She played the guitar as do I. So.....we would get together at her place to do some pickin'. Well, one time she brought out some old family stuff. There was a guitar pick that she said belonged to Wyatt. She offered to give it to me but I declined. But......she also showed me a pistol that she said was at the O.K. Corral fight. I had no reason to doubt her. Holding that gun was a thrill I'll never forget. Interesting woman. An old maid. Never married.... Long ago.
