No, separate small towns. Settled by German families who chose to keep a cultural association apart from the local area. Some of the Hispanic Catholics attend, but most choose to associate with their own cultural associates.
The German Catholic communities tend to be more wealthy farmers. The others tend to be poorer.
We see the same cultural division in some local German Lutheran based communities.
In the beginning it had to do with when they settled here.
My family has owned/operated farms in this county since 1889. I am comfortable in all those communities, but also see the self imposed division. I know most of the old families in all of those communities. Some really great people.
There few Catholic Churches in this area. Many more what Catholics would refer to as Protestants. I never liked that term, don’t feel I protest anything.
In TX I remember seeing in a Catholic magazine years ago how decorated those German heritage churches are. Like works of art.
