Glenys, I did extensive land searches with the LDS Orange Co. microfilm. First you get the indexes (prob. Grantee for your purposes) then follow your name. The indexes that I remember looking at in the later times seemed to bunch together names (in one family) as if a family of siblings who sold or inherited one property as a group. I think this might lead you back. I seem to remember that there was a Michael Jackson very early and very prominent in much of the early business of the county. I don't hae time now to look up more, but if you buzz me in a couple weeks I might be able to do it. Also, if I find more info sooner I will send via Or Co. list. Phoebe
