A few years ago we did a road trip through that part of Texas, looking at the "painted churches" (https://thedaytripper.com/the-painted-churches-road-trip/ - there are other itineraries). This article sparked that memory, as one of the painted churches is actually a Wendish church.
And yes, there's a painted church in Shiner as well! :-)
I hadn't heard of Wends until today. I'm Czech Texan, and more Czechs ended up in Texas than any other state, but of course we were still outnumbered by the German immigrants, so I'm not surprised by a subset of immigrants I didn't know about coming from that region. I haven't toured the painted churches, though many people I know have done so. Their story sounds pretty interesting, and I'm quite delighted to see this come across HN.
