In 1816 a great event happened to the little boy. His father emigrated to Indiana from Knob Creek (Thomas Lincoln had removed from the farm on Nolin Creek to one some fifteen miles northeast, on Knob Creek, when Abraham was four years old). “This removal was partly on account of slavery, but chiefly on account of the difficulty in land titles in Kentucky,” says his son. It was due, as well, no doubt, to the fascination which an unknown country has always for the adventurous, and to that restless pioneer spirit which drives even men of sober judgment continually towards the frontier, in search of a place where the conflict with nature is less severe—some spot farther on, to which a friend or a neighbor has preceded, and from which he sends back glowing reports. It may be that Thomas Lincoln was tempted into Indiana by the reports of his brother Josiah, who had settled on the Big Blue River in that State. At all events, in the fall of 1816 he started with wife and children and household stores to journey by horseback and by wagon from Knob Creek to a farm selected on a previous trip he had made. This farm, located near Little Pigeon Creek, about fifteen miles north of the Ohio River, and a mile and a half east of Gentryville, Spencer County, was in a forest so dense that the road for the travellers had to be hewed out as they went.

She was a friend of Thomas Lincoln and Nancy Hanks, and it is said that Thomas Lincoln had been her suitor before she married Daniel Johnston. Her husband died in October, 1818. In November, 1819, Thomas Lincoln went to Kentucky to seek her a second time in marriage. An incident of the courtship is told by Mr. J. L. Nall, a cousin of President Lincoln: “Uncle Thomas came back to Kentucky after the death of his first wife, Nancy Hanks, and proposed marriage to the widow Johnston; she told him that she would be perfectly willing to marry him, as she had known him a long time, and felt that the marriage would be congenial and happy; but it would be impossible for her even to think of marrying, and leaving the State, as she was considerably in debt. Uncle Thomas told her that need make no difference, as he had plenty of money, and would take care of her financial affairs; and when he had ascertained the amount of her indebtedness and the names of the parties to whom the money was due, he went around and redeemed all her paper and presented it to her, and told her, when she showed so much honor about debts, he was more fully satisfied than ever that she would make him a good wife. She said, as he had displayed so much generosity in her behalf, she was willing then to marry and go with
