Thus far I haven't learned much about Julius Triebess and his family, but thanks to this little item from January 1923, I have learned that Sophie Triebess' maiden name was Mankey.

Hobart Gazette 12 Jan. 1923.
With that information, I can be pretty sure Julius and Sophie were married in Chicago on June 11, 1901 (Cook County, Illinois, Marriages Index). According her Indiana Death Certificate, her parents were William and Dorothea* (Brockmiller) Mankey … but they are proving elusive in the census records.
Her brother, William Mankey, farmed the east side of Randolph Street south of the Grand Trunk tracks.
Reported at the bottom of that column, Dr. L.M. Friedrich had minor car crash somewhere south of the intersection of Randolph Street and E. 73rd Avenue, where the Ed Niksch place lay.
Over in the left-hand column is a (partial, maybe) listing of who was in the local dairy business in January 1923.
*In death certificates of other relatives, her name is given as Dorothy or Doris.
