My local library has San Diego City directories back to 1941. I found Dorothy Nelson(widow JC)in 1941+ in other years so I don't think she's your Dorothy. The central library in downtown San Diego has city directories going back to 1886 with some missing years. There is an obituary index from 1903-1930. That's not to say that there is an obit for every year. My local library does not have the SD paper going back to 1943. I'm sorry, not sure when I can make it to the downtown library but when I do, I'll look it up. In the meantime, if you wish to contact the libary, the phone number is 619-236-5800. The records are in the "California Room".
