There was a wave of Jewish migration from the Gouvernement Suwalki to and through Sweden. It began in 1850 and ended in 1900, and your ancestors that you have listed may well be among them. Among others, Carl Henrik Carlsson has published on this topic, e.g.
„From Suwalki to Sweden. Jewish Migration and Integration, 1850–1920“, in:
AVOTAYNU, Bd. XXXIV, Nr. 2 (2018), S. 33–37.
