Most important person in Lincoln's life

[Eva Elisabeth]

Same here, upon reconsideration (and Lincolnman Bill is just right) if a #1 was to determine, I, too, would go for one of the three. So, whom of the trinity would you consider the absolute #1? I tend to even think his stepmother rather than his mother.

I suppose the answer will be "yes" (I seem to recall so) - are there any books that entirely focus on A. Lincoln's parents or one of them?
