Any ideas on finding information for people emigrating from Russian Empire in the early 20th century?

Question

I'm having trouble tracing my relatives from the Russian Empire (now in areas of Lithuania, Belarus and Poland).  Any ideas/databases to assist with this?  I don't know if it's pertinent, but my relatives are Jewish.

Answer 1

Probably, the best place to start is Ellisisland.org.  They have digitized passenger lists.

Answer 2

Harbin, China had a large population of Russians. It was referred to the "Moscow of the North - according to one of my Chinese friends. The Russians built a railway there that linked Russia to the sea. My Russian grandfather was born there and I hope to find some connections for him.
