Answer the following question: Given the following context:  Trapper Jed Cooper and his two best friends Gus and Mungo are relieved of their possessions by some unfriendly Indians, so they seek shelter at a nearby army fort, commanded by Captain Riordan. The captain recruits the three men as scouts. Also at the fort is Corrina Marston, waiting for her missing husband, Colonel Frank Marston. Jed quickly falls in love with Mrs. Marston, sensing her ambivalence about her husband; when the colonel returns, he is revealed to be an unmitigated tyrant. Colonel Marston is driven to redeem himself after a disastrous battle at Shiloh, where over a thousand of his men were killed unnecessarily. Marston wants to attack the regional Indian chief, Red Cloud, believing this will restore his good name and return him to the battle back east. He ignores the fact that most of the men at the fort are raw recruits, hopelessly outnumbered and completely unprepared for the vicious fighting they will face with the Indians. Jed is faced with the decision of letting Marston go on with his mad scheme, or finding a way to do away with him.  answer the following question:  What is the full name of the person that the woman the trapper falls in love is married to?
Answer:
Frank Marston
