I am related to a Joseph Joaquin who moved from hawaii to the Hayward are of California. What is your grandmothers birthday? My info says he married a Mamie Cambra. I have joseph's birthday as Apr. 20 1902 and he died in July 12 1981. His father's name is Manuel Joaquin. I do not know what part of Portugal they are from. I'm sorry I don't know if this is who you are looking for.
