Off the top of my head I can't remember if they exchanged letters about Hamilton between them. But I do remember from the Chernow book that Abigail Adams wrote to her husband about Hamilton quite a bit. She hated Hamilton from the beginning. After he campaigned against Adams for President it got worse; then the Reynolds affair just made her feelings even stronger. At one point she wrote something about not even wanting to say the name of the ship he was embarking on because of how vile he was. There was one letter where she was so angry about him that she begged her husband to burn the letter after he read it because she was so vitriolic about him and dared not write so freely again.

Although oddly she had a lot of praise for him as Secretary of the Treasury and thought he was doing a good job. She just loathed him personally.

Thanks for that information, some great insite.
