Answer 2

Hey friend,
Here's your answer,
When John met Colonel Allyn, he told him everything about him and his code of living - that a man should be decent and right in his home town. When the Colonel referred to Sir Courtenay Pescud in the time of Charles I, John denied any link with him. 
He said that he belonged to a common family. Then he narrated him a story. The Colonel laughed. He too, told him a story. He seemed to have no objection if he proposed to his daughter. 
John again met Jessie and tried to convince her about the sincerity of his proposal. Eventually, Jessie agreed, and both of them got married..........

Hope this helps!!!!
