Amos referred to

"Mrs. Lottie T. Something",

Amos, the old convention was that a divorced woman carried the honorific "Mrs." because she was no longer a Miss (an unmarried and presumably inexperienced woman), but she no longer "belonged" or "was an extension" of Mr. Something, so she was Mrs. Lottie T. Something, assuming she had not taken back her maiden name when divorcing or divorced.   

A widow, on the other hand, still had that connection with her deceased husband, so she was "Mrs. John T. Something" until and unless she remarried, when she became "Mrs. Clarence Othername".   

And of course one might refer to the ex-Miss Jones as "Lottie Jones Something" and later "Lottie Jones Something Othername".
