Anybody here who knows Texas Germans?

Its true German is the largest white ancestry group in the US. Although most I don't think they hang on to their roots as much as the Irish or Italians due in part they immigrated earlier and blended in with the culture. Many changed their names during the world wars due to anti German sentiment during that time period. For example my step grandfathers fathers original name was Werner, which was later changed to Warner, due to his shop in upstate NY being vandalized.

The German influence is still alive and well in southeastern and south central Pennsylvania with the Pennsylvania Dutch. Many have retained their distinct accents and culture.

The Germans and the Czechs settled mostly in central Texas Hill Country, but really all over. Many cen-Tex towns have German names and are full of old gothic style churches built in mid 1800's--some of the finest replicas of Baroque archtiecture outside of Germany and Austria, known as the painted churces of Texas http://www.youtube.com/watch?v=0dNhdbAhRLM

The German immigrants in the Texas Hill Country were staunchly anti-slavery and pro-Union. After Texas seceded, Anglo-Texans descended on their communities with a vengeance, killing dozens and burning their farms and homes for refusing to sign "Loyalty Oaths" to the Confederate Government. After the war, the bones of several victims were gathered and buried in Comfort, Texas, under this monument, which was dedicated in 1866. http://www.civilwaralbum.com/misc14/comfort1.htm

Other than that I can't speak much to the linguistic element. Most Germans became Americans so long ago and, I guess the only difference one could note is that southerners with the distinct southern accent are probably more descended from the English and Scots-Irish, while Germans would be more mono toned. But even that's a generalization as many Germans certainly comprise much of what you'd picture as Texas and Southern culture.

Ya. Das ist gut. Of course, we here in Berlin are tracking what you write.
