We don't have the SD paper obits for 1991 in my local libary but I'll look it up when I go to the central library downtown San Diego. It may take me a while to get to it. I did find a Pedro T. Acosta in the 1984 city directory. He lived at 4541 N. 33rd Street #8.
You and I have been tracking people from NM to Imperial County,CA. May I ask, did you ever locate any family of Cecilia Duran Baros, granddaughter of Juana Duran from San Miguel Co, NM.? Gloria
