One was a Bible that was either distributed to Congressmen or school-children. The others were "The Lives of the Founders," one version for girls, and one for boys. According to the guest, they were ubiquitous textbooks of the early 19th century.
I don’t think they were two versions, but two different books.
The second book was about the “Wives of the Founders”
I have a copy of The Jefferson Bible. Coincidentally, my son and I just pulled it off the bookshelf last weekend. The other two books were Wives of the Founders and Lives of the Signers of the Declaration of Ind. Just ordered those two on Amazon.
