A Jacob Schiff, this time arriving from Poland, came to New York in the early 1900's. He was a cabinet maker who later made his home in New Haven. His son Irwin was a prominent figure in the US tax protester movement. He died in federal prison in 2015 while he was serving a 13 year sentence for tax evasion. His son Peter, however, has been a successful financial investor and writer. A Schiff family from Lithuania came to Boston in 1906 where the husband worked in the butcher's trade. Their grandson Adam became a Californian Congressman in 2001.
