Looking at Gerhart Hauptman - I have Uber and Tham ancestors in Nieder Wolmsdorf and Kauder near Bolkenhain, which appears to be about 20km from Bad Salzbrunn where the WikiTree Profile says he was born. But the Find-a-grave memorial puts his birthplace near Wroclaw. Wikipedia breaks the tie, listing his birthplace as Bad Salzbrunn.
His de.Wikipedia.org web page is far more extensive than the English one (of course). It tells us that his father was Robert Gerhard Hauptmann, his mother Maria Hauptmann nee Straehler. He had three older siblings. That German site also names 3 sons from the first wife and one son from the second, and a granddaughter who has a de.Wikipedia.org page as well. Maybe there are connections through his mother or those five descendants.
I keep editing this as I read more. This granddaughter, Anja Hauptmann (born 1943, still living), is also the granddaughter of conductor Max von Schillings -- another definite Notable. But no help there--apparently, he has no WikiTree profile yet. He's not the kind of person I'd care to honor--a very ardent anti-Semite--but an obvious notable nonetheless.
As far as Ancestors in Silesia, I have few useful resources in the area to help find a connection. If any Ubers or Thams show up in his ancestry, maybe we can give it a shot.

Long edit added a few hours later:
One connection of Gerhart Hauptman to WikiTree's global tree begins with Pietro Antonio Brentano. (I'm 26 degrees from him which means he is connected to the global Tree. It's a cool connection. It goes through Cozima Liszt Wagner, daughter of famed composer Franz Liszt and wife of famed composer Richard Wagner.)
The children of Pietro's first wife are not entered in his WikiTree profile. See the Frankfurt line of Brentanos on this German Wikipedia Page. Look for great-granddaughter Johanna (1839-1885). She is Johanna Antonia Brentano, who married Carl Xavier Hubert Schillings (1821-1896) and is the mother of Max von Schillings.
Max had an illegitimate daughter (I assume) named Barbara Schneggenburger. See Anja Hauptman's Wikipedia Page for the source of this information. Barbara is Anja's mother, wife of Benvenuto Hauptman, who was Gerhart Hauptman's son by his second wife.
If I find time, I'll add all those profiles, but I have a lot on my to-do list.
By the way, note that Pietro Antonio Brentano is a notable profile that has no profile manager. He could use some love. None of his ancestors are listed on WikiTree and they go back to ca. 1330 (see the above linked Wikipedia page on the Brentano family).
