An update to the Poskanzer Family Tree has been posted at: http://art.poskanzer.org/PoskanzerTree/ .

There are new clear photos of tombstones in Albany cemeteries nicely  taken by Susan Poskanzer, with careful translations of the Hebrew by  Olga Zabludoff: http://art.poskanzer.org/photos/cemeteriesAlbany/index.html .
 
Jane Frueh has kindly added extensively to the Rosenberg line, with  many dates, etc.
 
Progress has been made on the Ukraine branch of the family which  probably started with Abraham Pushkantser, born 1872 in Rumshishok,  Lith. region of Russia, and who migrated about 1900 to the Ukraine.  Max Pushkantser of St. Petersburg has been a great help. His old  photos are at http://art.poskanzer.org/photos/Max/index.html . He also obtained a  police report from 1924 from the State Archive of Republic of Moldova  about a Pushkantser who Illegally crossed the border from USSR to  Bessarabia. It was translated from Romanian to Russian and then by  Max to English. I found two Pushkantsers from the Ukraine who were  killed in the Red Army in World War II, two more who died in the  Holocaust, and four who are listed as survivors, one of whom now  lives in Queens, NY. Marc Diemont (Poskanzer) was born in Kiev in  1898 before coming to the US at the age of 6. Even my grandfather  David Chaim Poskanzer went to "deep Russia" before emigrating to the  US. As far as I know no Pushkantsers remain in the Ukraine today. The  most famous living person from the Ukraine branch of the family  (based on the number of hits at google.com.ua) is Natalia Andreeva  Pushkantser, a concert pianist now in Stavropol, Russia.
 
A bridge engineer, Eli Pushkantser, and his daughter, Miriam, lived  in Germany and died in the Holocaust. Sonny Poskanzer had heard of  them, but we have not been able to fit them into the tree.
 
The origin of the surname Pushkantser was probably the village  Puszkance. I found it in two early 19th century references, but have  not found the modern counterpart. For details see http://art.poskanzer.org/PoskanzerTree/Pushkantser.html .
Olga Zabludoff and I thank all of you who have helped and hope you  continue to send additions and corrections, as well as old photos.
