I found your recent post about visiting the site of the old St. Joseph's Orphanage in Tuscon. My mother and her 2 sisters were dropped there by their parents on August 30, 1926. My mother, Eva Yanez, was only 4 years old at the time.
I am particularly curious to learn how a Mrs. J. Knox Corbett was associated with the orphanage. Her name appears in some paperwork we found with the help of an attorney.
From what my mother remembered, they released her from the orphanage at a very young age, possibly 15. Her memories were fond; always having food, some toys, and the gentle Sisters that cared for and taught the children.
I would also appreciate hearing results from your research on this site! If I can be of any other assistance, please feel free to contact me.
