Found it - Dorritt was a daughter of Daniel Bitler and Maude Conwell. After living in Tulsa, she ended up in California and died 21 May 1969 in San Francisco. Olpe Heritage book listed her as deceased in 1977, so it all fits. There is a Guy W Miller that died in Alameda Co, CA (b. 11 Jul 1900, d. 2 Feb 1989), but I can't confirm this was Dorritt's husband ... yet.
