I used to live in Santa Clara, CA, and there was a large Portuguese community hall just down the street from where I lived and they would parade to the church on many Sundays with the little girls all dressed up, etc. So, I'd assume there must be a sizable population in the SF Bay Area.
I found their facebook page. Maybe someone on their page could give you some ideas:
