My ancestry goes into the Santa Isabel Reservation. I don't have all of the info yet. There is a workshop in Old Town San Diego November 17, 2001. Check my posting dated 10-29-2001 under Juan Maria Osuna for more info. I believe I'm related to Ed Osuna, Gilbert Osuna and Florence (Osuna) Ponchetti that actually lived on the Santa Isabel Reservation (1st house on the left as you enter the gates). The connection is with Julio or Leandro Osuna.Florence knew my Grandfather Ramon N. Osuna of El Cajon who was the last child known to be born on Rancho San Deguito. My last contact with them was in June of 1987.
