Our home was built by a McGregor (or MacGregor) in 1946 -- please help us find information on this architect!?

The home is in Albany, California, is a narrow, vaguely Spanish/Mediterranean design, and is apparently part of a "MacGregor style" that I can find absolutely no information about on this vast internet. Help!|||the macgregor style was not unlike the Johnson style in that Macgregor probably came back from the war and built a few homes in a few subdivisions, and made a few bucks.
