Sometimes Fortuna smiles on you. I was able confirm in the records of Riga Cathedral that Hugo Carl Taube was indeed the son of goldsmith Adam Bartholomäus Taube and his wife Juliane Sophie Lukaschewitz; an older son, Nikolai Adolph Taube, was born on 5 Apr 1866.
Further digging revealed that Adam Bartholomäus Taube was born on 17 Sep 1834 in Riga, the son of Adam Bartholomäus Taube & Catharina Künstler (I could not make out the elder Taube's occupation, but it was definitely not a gold or silversmith), and was baptized at Riga Cathedral on 17 Oct 1834. He married Juliane Sophie Lukaschewitz, age 30, on 23 Apr 1865, at St. Gertrud Old Church, Riga; his occupation is listed as a goldsmith.
I have not yet been able to find a death record for him, but will keep looking. However, I think the abundance of evidence thus far makes the attribution of the ABT mark to Adam Bartholomäus Taube all but certain.
