I am new to the SF mailing list so if I've missed the answer to my question(s) please let me know. In later life, a brother of my grt. grt. grandfather use to spend the winter months in SF instead of his usual residence in Denver, Colorado. This man owned property/buildings in SF but everything was destroyed in the 1906 earthquke. I have a photo of him standing next to the rubble of one of his buildings. Were all the land records previous to 1906 destroyed in the earthquake? If not how would I go about trying to obtain the records? Carolyn Murphy Monument, CO.
