Laurie's daughter took a photo of Abraham Lincoln!

Mary never called him like that either, did she? (Only "father", or "Mr. Lincoln" AFAIK, and "my dear husband" in letters.)

I have read this also. She never called him "Abe." Even his letters and telegrams to her were usually (possibly always; I have not checked every single one) signed "A. Lincoln."
