How did Lawrence get its name?

Lawrence is awesome, right?  But what is the deal with Lawrence, Massachusetts and Lawrence University?  Well, all three are connected:

Samuel Lawrence fought in the Revolutionary War.  He became a successful Massachusetts businessman and had four sons who built a huge textile business and Lawrence, Mass was named for them.  One of the sons, Amos, had a child of the same name who grew to be a successful businessman of his own and helped the Immigrant Aid Society to send settlers to Kansas in hopes of creating a free state.  These settlers chose to name Lawrence, KS for him.  He also held land in Wisconsin and helped found a school there, now named Lawrence University.
