Thank you for posting a response. A lot of research has been accomplished since my original post. That said, I am still interested in any information about the FULLER line you may be able to share.
In the past five years, I have found that Lotah and George (Jr.) moved to Tucson, where he was employed as a real estate "caretaker" in 1930. The precise meaning of that designation has yet to be determined. At least two of their children survived into adulthood; one remaining, from what I can tell, in the Arizona area and the other eventually moving to Callifornia.
I have also done a little research on the line of Sarah and her husband, Tillotson. Nevertheless, there is much more on this line which I would like to learn. Please contact me privately to discuss further.
