That night I looked up their LA County Assessors website online and found a couple adjoining addresses and sure enough, the next day with the neighbor addresses they could find the land lots. What you see is a tract map of the property and on the facing page, a list of the owners of each lot in the map of the block, or whatever. The book may cover 1 to 10 years, depending on how much space the book has. Its lists the tax value for each year, with lot and parcel number assigned to each owner. If there was a sale, the new owner's name is written to the right of the old owner, but in the older books there is no DATE of the transaction. So it might be anytime during the length of time of the book. Is that clear??? Definitely head ache provoking.
With high piles of assessors mapbooks brought to me, I dutifully went through each one, like a title search. I think I was looking for an Assessors ID Number. Something that doesn't seem to exist for these records of early 1900. And there was no nicely added date of any land sale/transfer. As I went down through the books I hit a dead end for both the addresses as the note on one books that says "where to look for the prior book" came to an abrupt end - with "Dead Page" being listed on the computer that the Keeper of the Mapbooks looks at. So my search only went back to 1940's on those addresses.
I'm going to return to the Norwalk office to see if there are any more "deed-like" documents I can find there, beyond what I found last year.
Hopefully when I get to the Jamboree in Burbank I'll have found some more information on the land transactions of my great-grandparents - Frank and Edith Blanding.
