The paternal grandfather of Mary Todd, General Levi Todd, was born in 1756, was educated in Virginia, and studied law in the office of General Lewis of that State. He emigrated to Kentucky, was a lieutenant in the campaigns conducted by General George Rogers Clark against the Indians, and commanded a battalion in the battle of Blue Licks, August 18, 1782, where his brother, John Todd, was killed. He succeeded Daniel Boone in command of the militia, ranking as major-general, and was one of the first settlers in Lexington, Ky. February 25, 1779, he married Miss Jane Briggs. The seventh child of this union, born February 25, 1791, was Robert S. Todd, the father of Mrs. Lincoln. On her maternal side Mrs. Lincoln was highly connected. Her great-grandfather, General Andrew Porter, was in the war of the Revolution. He succeeded Peter Muhlenberg as major-general of the Pennsylvania militia. Her great uncles, George B. Porter, who was governor of Michigan, James Madison Porter, secretary of the navy under President Tyler, and David R. Porter, governor of Pennsylvania, were men of ability and distinction. Her mother, Anne Eliza Parker, was a cousin of her father, Robert S. Todd. The latter had served in both houses of the Kentucky Legislature, and for over twenty years was president of the Bank of Kentucky at Lexington. He died July 16, 1849. To a young lady in whose veins coursed the blood that had come down from this long and distinguished ancestral line, who could even go back in the genealogical chart to the sixth century, Lincoln, the child of Nancy Hanks, whose descent was dimmed by the shadow of tradition, was finally united in marriage.
