I just know Gillespie very well because my parents have a place up there. The old timers (of whom there are very few around because they'd be past 70, but would have been children during the 1920s) still spoke with a strong German accent. Imagine what accent their parents (who voted in 1924) spoke with, if they even spoke English.
Their children still have a slight German accent, but the young kids (30-35 and younger) have no accent.
The
New Braunfels Herald-Zeitung dropped their German language section in 1957.
