Blucher as either a name or a word in German does not translate to “glue” in English.
Frau Blucher would have to have been named Kleber, which does translate as “glue”.
The name was used as a meme against German-fear, and gotten it is said from the name of the Prussian Cavalry General who rescued Wellington from Napoleon at the Battle of Waterloo.
No more Germanic name than the Prussian Blucher.
Mel Brooks told Teri Garr (RIP) that the name made horses whinny because it meant “glue”— he was pulling her leg.

That’s funny! All these years I was mistaken.
Leave it to Mel Brooks to yank someone’s chain. I love that movie!
Thanks for the correction.
