By the 1850s, the railroad industry was moving west and Illinois found itself becoming a major hub for various companies. Abraham Lincoln served as a lobbyist for the Illinois Central Railroad as its company attorney. Success in several court cases brought other business clients as wellbanks, insurance companies and manufacturing firms. Lincoln also did some criminal trials. In one case, a witness claimed that he could identify Lincolns client who was accused of murder, because of the intense light from a full moon. Lincoln referred to an almanac and proved that the night in question had been too dark for the witness to see anything clearly. His client was acquitted.
About a year after the death of Anne Rutledge, Lincoln courted Mary Owens. The two saw each other for a few months and marriage was considered. But in time Lincoln called off the match. In 1840, Lincoln became engaged to Mary Todd, a high spirited, well educated woman from a distinguished Kentucky family. In the beginning, many of the couples friends and family couldnt understand Marys attraction, and at times Lincoln questioned it himself. However, in 1841, the engagement was suddenly broken off, most likely at Lincolns initiative. They met later, at a social function and eventually married on November 4, 1842. The couple had four children, of which only one, Robert, survived to adulthood.
