Dear Mexican: Our grandparents came from Mexico. The entire next generation spoke Spanish. However, in my generation, pretty much none of us do. One cousin's daughter does because the cousin married a fluently bilingual spouse. Most white people I know have long ago lost both, generally, awareness of what their actual ethnic roots are and the original language their people came to America with, when it wasn't English. Heck, British English can be pretty confusing. What me and my cousins, and most of our kids know of Spanish is what we learn in Spanish classes.
