I don't have any information beyond 1930 but I can go back earlier. It looks to me like the Zabriskie store was there first. The Gomez family doesn't show up as operating a store in 1910 even though they were in the area at the time. The Zabriskie operation on the other hand goes back at least to 1910. The Gomez operation must have started up sometime between 1910 and 1920.
