I attended the same school as my mother did. It was a three room country school. However when she was attending it was taught in German and Spanish Hence the need for three rooms.
When my brothers attended it was taught in English and Spanish. By the time I attended it was only English. It was thought natural for children to learn in their native languages in pre-WWII Texas.
I later spoke with a Spanish descent friend. His comment was, That it was very hard for rural Spanish speakers to learn English in that day. Most of the Germans spoke all three languages,. They conducted business with the Hispanics in Spanish. I know my father was highly regarded for his ability to speak Spanish.
I, myself, speak German very well and would often do the translating for my Army unit in Germany. One of the few extra duty jobs I actually relished.
Oh! and FWIW, My family is listed in the 1880 census as being here since 1873. For those who wonder about loyalties due to our being capable of speaking another language. We have been involved on the U.S side in every war since arriving.
Interesting history.
I was just tweaking the fans of historical revision around here. No offense meant or taken I hope.
