Notes:
There were several people from the Thurm family in the bottling or Saloon business in Washington DC.
Julius T. Thurm (1829-1899)² seems to be the father or grandfather of the other Thurm family members. He started a Saloon in the Good Hope section of Washington DC staring about 1884. Amelia C. Thurm, Julius's wife, appears to have taken over Julius's saloon in Good Hope for 1 year (1900) after Julius passed away. Other Thurm family members seemed to take over the saloon after that.¹
Good Hope, Twining City, and Anacostia are all in the same general area of SE Washington DC, with Good Hope being just north of the Anacostia river, and Twining City & Anacostia being just south of said river.

Herman G. Thurm (1854-1901)³ was Julius's son. Based on city directory listings, he started out as a Saloon owner in 1880, then switched to a bottler in 1887, and continued as both a bottler and saloon owner from 1894 until his death in 1901¹.

Gustav Adolph Thurm (1881-1922)⁴ was Herman's son (Julius's Grandson). He ran a Saloon business in Good Hope from 1904-1914. I suspect it was the same Saloon his Grandfather owned, but I'm not sure as the exact address is not listed in the city directories, only that it was in Good Hope.¹

Paul Thurm (1860-1890)⁵, Herman's brother, was listed as a bottler at 520 8th Street SE in 1886. Herman was listed as a Saloon owner at that same address in that same year. So I'm guessing that Paul started the bottling business at his brother Herman's saloon, but in subsequent years Herman is listed as owning that bottling business and Paul was listed in the residential section as a bottler (presumably working for his brother).
