Descendants of Taube Feige's grandfather Strasberg

This family tree is waiting for some actual names to go at the top. 
On a family tree put together years ago Sarah Devorah carries the last name 
Shimberg, but the line carries the Strasberg name. Was Shimberg an error, 
or was it changed to Strasberg? This needs research. The name Shimberg 
was known in Syracuse, NY and in the same areas of Lithuania that 
the family came from.
