Help finding Ancestors: Rubenstein, Phillips, Kreeger, Perlstein #usa


I am hoping someone can shed some light on our ancestors’ early family.

 Our earliest known relatives are Louis Rubenstein (1841-abt 1921: New York?) and his wife Henrietta Pearlstein (abt 1842-1880: Chicago); and David Aaron Phillips (bef 1816-1858: Jamaica) and his wife Catherine Isaacs (bef 1816-1875: Jamaica); and George Isaac Kreeger (1804-1853:Louisiana).

So, where were Louis and Henrietta born?  Russia, Germany?  Where did he die?  They say he remarried after Henrietta died.  David Phillips and Catherine Isaacs, we believe were born in London, England, to whom?  And, George Kreeger, we think was born in Latvia.  Any info would be very appreciated.
