Searching for the Salzman Family

My great-aunt passed away in 2002.  She had built a family tree for many sides of the family going back a few generations.

Unfortunately, she also made some mistakes, too.  Unfortunately, some of these mistakes meant that it took longer to find some families--by which point some of the older generations have passed away.

What we do know is that Kassel Salzman immigrated to America in 1896 after traveling with his wife, Pauline, and children from Russia.  What we do know is that he had quite a few children: Charles, Max, Annie (Anna), Maurine (Mary), and Sadie.

We know that Kassel was convicted of larceny in the early 1900s and went to prison where he ended up dying in 1911.  We have managed to get in touch, finally, with Anna's descendants so as to update that branch of the tree.  But outside of that, we're stuck.  When it is a common name (Saltzman became Salzman or Solzman), it makes it harder with marriage records, etc.  I've found obituaries but when they don't mention siblings, it's hard to confirm whether that's the one I am looking for.

We know that the name was Saltzman in the 1900 census and Salzman when the 1905 census was recorded.

But we're stuck.  My only hope now is for a distant cousin to find this, get in touch, and help us rebuild this branch.
