In 1667 they travelled to Amsterdam, where Krzysztof apprenticed with Adriaen Backer, and Teodor with Gerard de Lairesse. In 1682, Teodor moved to Hannover before eventually moving to Poland in 1706, where he died.
Krzysztof remained in Amsterdam, where he painted portraits and genre pieces. He also collaborated on prints for Jacobus Houbraken, Daniel Willink, and Johannes Brandt (son of Gerard Brandt). He died in Amsterdam.
