If I remember correctly? Lincoln was born in Virginia and moved by his father to Illinois as a boy of 12? So he may not of had as much of an accent as a native born?
Since there are no recordings of anyones voice from back then, we will never know!
Abraham Lincoln was born at Sinking Spring farm in what is now LaRue County, Kentucky. When he was two, his family moved to another farm a few miles northwest on Knob Creek. Knob Creek bourbon should not be held against them.
Thomas Lincoln lost two farms because of bad land titles. Someone wanted the land and challenged the title, there was a survey and that was it. It happened a lot. In 1816, the Lincolns crossed the Ohio and and settled at Little Pigeon Creek in Spencer County, Indiana, where Thomas wouldn't have to compete with slave labor. That is where Abraham Lincoln grew from a 7-year-old boy to a 21-year-old man.
In 1830 there was an outbreak of Milk fever all along the Ohio. Milk fever is a disaster if you keep dairy cows. There was no question of returning to Kentucky, so the Lincolns moved to Illinois and settled on public land 10 miles west of Decatur. In 1831 the family moved again, to a farm on Goosenest Prairie south of Charleston in Coles County, Illinois. Abraham Lincoln never lived there and visited infrequently. He returned there for his fourth debate with Stephen Douglas at the Coles County Fairgrounds.
I have relatives all over southern Illinois and southern Indiana. People there don't all sound alike. Educated people sound more like Shelby Foote. Good ol' boys sound more like Dennis Weaver on
Gunsmoke. But they all drawl, it is a distinctive regional accent. One of my cousins went to school in Normal and she got really tired of hearing people call her a hillbilly.
People who met Lincoln were impressed by his high pitched voice. They were not favorably impressed. Lincoln did not have an actor's or a singer's beautiful voice. He was a great orator, but that was all about the quality of what he said. And he had the ability to speak "like a book" in long, complex sentences and paragraphs that most of us need two drafts to set down on paper. There is a brilliant example of this in
Lincoln, when Lincoln explains why the 13th Amendment must pass. Daniel Day-Lewis caught Lincoln's manner perfectly, even though he gave him a Peter Jennings accent.
No one commented on Lincoln's accent, so I assume he shared the regional speech pattern.
We have no recordings of Lincoln's speech, but part of it survives in his writings.
