So very sorry to belatedly learn of Don's passing via the internet. I had found his articles on the Jacksonville area extremely informative, particularly his writing about the Arnot bakery, where my grandparents worked in the 1920's. We corresponded several times in 2016 and I was able to reciprocate his generosity in some small way with photos of the Arnot company picnic of 1928 and copies of my grandfather's reminiscences of working for the Arnots, which Don generously added to his historical archives. Again, my sincere condolences, as I did not know Donald personally, but his work greatly enriched my own family history research.
