Mary Ann Todd Lincoln (December 13, 1818 - July 16, 1882) was the wife of the 16th President of the United States, Abraham Lincoln, and as such the First Lady of the United States from 1861 to 1865. She dropped the name Ann after her younger sister, Ann Todd [Clark], was born, and did not use the name Todd after marrying. Mary was a member of a large, wealthy Kentucky family, and was well educated. After finishing school during her teens, she moved to Springfield, Illinois, where she lived with her married sister Elizabeth Edwards.

Mary was born in Lexington, Kentucky as the fourth of seven children of Robert Smith Todd, a banker, and Elizabeth "Eliza" (Parker) Todd. Her family were slaveholders, and Mary was raised in comfort and refinement. When Mary was six, her mother died in childbirth. Two years later, her father married Elizabeth "Betsy" Humphreys and they had nine children together. Mary had a difficult relationship with her stepmother.  From 1832, Mary and her family lived in what is now known as the Mary Todd Lincoln House, an elegant 14-room residence at 578 West Main Street in Lexington, Kentucky.  Mary's paternal great-grandfather, David Levi Todd, was born in County Longford, Ireland, and immigrated through Pennsylvania to Kentucky. Another great-grandfather, Andrew Porter, was the son of an Irish immigrant to New Hampshire and later Pennsylvania. Her great-great maternal grandfather Samuel McDowell was born in Scotland, and emigrated to Pennsylvania. Other Todd ancestors came from England.  At an early age Mary was sent to Madame Mantelle's finishing school, where the curriculum concentrated on French and literature. She learned to speak French fluently and studied dance, drama, music, and social graces. By age 20, she was regarded as witty and gregarious, with a grasp of politics. Like her family, she was a Whig.  Mary began living with her sister Elizabeth Porter Edwards in Springfield, Illinois in October 1839. Elizabeth, married to Ninian W. Edwards, son of a former governor, served as Mary's guardian. Mary was popular among the gentry of Springfield, and though she was courted by the rising young lawyer and Democratic Party politician Stephen A. Douglas and others, she chose Abraham Lincoln, a fellow Whig. Answer this question using a quote from the following article:
