Hi Sally, Yes there is an index to both the IOOF Lawn Memorial and the Old Mission Cemetery the problem is if there is no marker the grave is not in the index. The cemeteries were walked and recorded by volunteers of the SLO Gen. Society and the actual burial records were not compared. If you are not in a hurry, I will try and find the site for you. I live in Coalinga but go to SLO on a regular basis for research. I was born and raised there and have only been out of the area a year! My main focus is on early California Families, part of my family is 9th gen. and another came after the civil war, settling first in Hollister then SLO, so have alot of roots there. I can check with the cemeteries officers to see if there is any information in the burial records. I can also check the Recorders office if you haven't done that already. For IOOF, if you e me the name and relationship, asking me to access the file, the office will allow me to transcribe or copy what is there. The Catholic Cemetery also has a more complete file than the index. IF stones are there, I also can photograph. The Catholic cemetery has been re-located twice, the first in the Mission Church quadrangle. After 1860, on Higurea St between Carmel and Pacific Sts which dead ended at the cemetery. In 1877 a law was passed which forbid burial inside the city limits.. so the 3rd site was opened, alot of markers and records have disappeared with the re-locations. At one time the Catholic Cemetery was the only cemetery. I check the Temple Index to Mission Records for your early names if you send them to me. Doreen
