Names ending in L

Have you ever noticed the curious configuration of quite a few names in central Minnesota?  They're names that (maybe by accident) are a word with an L added to it, like:
BRANDL
STANGL
GANGL
SCHOTL
REISCHL
PITZL
PESCHL

The names in red are Morrison Co names, and the others are from the St Cloud Directory, but they're familiar, too.
We found L-ending names in the Bohemian church books, coincidentally those in red.  I wonder if this a significant formation in Bohemia or in Germany, or Silesia?  Does anyone know?
(Oh, I forgot LOL ☺)

Our good friend Anon happens to teach German, so this sort of information is something he probably realized years ago:


"The  Stangl, Brandl, Gangl, Peschel - which was Peschel around Buckman for over 100 years -  are all dialectical derivatives without the proverbial - el - spelling prevalent throughout the German empire.  The -gl and -dl were prominent in names of our ancestors from Bohemia and Austria.  It is a common dialect form found throughout the Austrian Empire, and also Bavaria, which controlled much of Bohemia at one time.  Maidl was a common name west of Buckman years ago too.  One can always tell that those people are basically Austrian by birth, just like Loidolt, since Germans don't usually use an -oi- spelling in anything.  Again an Austrian dialect derivative".


Thanks, Anon--this is one less thing for me to wonder about.  So, if a German speaking  ancestor has a name ending in -l, it's a pretty good indication that they were Austrian-cool!
