Lincoln was at this time the father of two sons: Robert Todd, born on the 1st day of August, 1843; and Edward Baker, born on the 10th of March, 1846. In a letter to his friend Speed, dated October 22 of the latter year, Lincoln writes: "We have another boy, born the 10th of March. He is very much such a child as Bob was at his age, rather of a _longer_ order. Bob is 'short and low,' and I expect he always will be. He talks very plainly, almost as plainly as anybody. He is quite smart enough. I sometimes fear he is one of the little _rare-ripe_ sort that are smarter at about five than ever after. He has a great deal of that sort of mischief that is the offspring of much animal spirits. Since I began this letter a messenger came to tell me Bob was lost; but by the time I reached the house his mother had found him and had him whipped. By now, very likely, he is run away again." December 21, 1850, a third son, William Wallace, was born to him; and on April 4, 1853, a fourth and last child, named Thomas. "A young man bred in Springfield," says Dr. Holland, "speaks of a vision of Lincoln, as he appeared in those days, that has clung to his memory very vividly. The young man's way to school led by the lawyer's door. On almost any fair summer morning he would find Lincoln on the sidewalk in front of his house, drawing a child backward and forward in a little gig. Without hat or coat, wearing a pair of rough shoes, his hands behind him holding to the tongue of the gig, and his tall form bent forward to accommodate himself to the service, he paced up and down the walk forgetful of everything around him and intent only on some subject that absorbed his mind. The young man says he remembers wondering in his boyish way how so rough and plain a man should happen to live in so respectable a house. The habit of mental absorption, or 'absent-mindedness' as it is called, was common with him always, but particularly during the formative periods of his life. The New Salem people, it will be remembered, thought him crazy because he passed his best friends in the street without seeing them. At the table, in his own family, he often sat down without knowing or realizing where he was, and ate his food mechanically. When he 'came to himself' it was a trick with him to break the silence by the quotation of some verse of poetry from a favorite author. It relieved the awkwardness of the situation, served as a 'blind' to the thoughts which had possessed him, and started conversation in a channel that led as far as possible from the subject that he had set aside."
