A quick post script.
I picked up Arey's trail in the Oakland directories. He is listed as a "chemist" in 1889, residing at 1222 Franklin in Oakland. No mention of him for a few years until he resurfaced in 1903 as a Real Estate salesman living at 166 E. 15th St. There is no mention of him in society directories and no record of him ever having a telephone. This indicates that he lived a pretty meager lifestyle and, like the used car saleman of today, was an opportunist always looking for greener pastures. Pastures that seem to elude him.
