This site is a collation of Henry Basewitz, presumably of Russia. This site also includes descent from Dora Sabath, who was married to Henry. As I have no other information about her family at this time, creating separate line of descent would be completely redundant with that of her husband.
We know of Henry and Dora from their daughter, Basche's, death certificate. This provides no information about their origin but we might presume it is in the vicinity of Pinsk, Russia as that is where Basche was born. Pinsk is now part of Belarus but, in the 19th century, was part of the Russian Empire. The map image is a segment from the Cambridge Modern History Atlas showing part of the Russian Empire at about the time of Joseph with the location of Pinsk marked.
The information comes from various Basewitz descendants, both in my line and others.
