Dusty: Thanks for sharing the titles of these books. I will make a point of reading them as I'm sure they will provide great insight. As for the letter, my grandmother was 5-years old when her father filed enrollment in 1901. Some of her siblings, who were not born yet, were not listed in Bannister Allen's case file. Therefore, something had to happen after the 1902 rejection for them to have received the letter. I assume, but do not know for certain, exactly when the letter was received and from where. My grandmother died in Chicago in 1974. One of her nieces is still alive. She knows that her mother, who had not yet been born in 1901, had received one of the letters I'm referring to. I hope you can understand my hesitation and my need to know. Again, thanks for the titles. Lori
