If I may add, the Garvanza name disappeared some time by the mid 20th Century, the area being considered part of Highland Park. It was later revived in the mid or late 90s, I believe. By the time I moved to South Pasadena in 1998, the Garvanza district/neighborhood signs were already in place.

That's news to me! I can't imagine where it would be.
