I've found a family with the surname Greenstein in Boston. The parents are Louis Greenstein born 1870 and Sarah born 1878 (possible maiden name Barrett), both from Russia.Three of their children were born in Russia; twins Rose and Irving in 1896, and son Harry born in 1898, but last son Hynean was born in Massachusetts in 1906.
Benjamin Greenstein (born 1879) lived on Washington Street in the town of Haverhill, MA in 1920 with wife Eva, and a son whose name is unreadable, a second son named George, daughter Charlotte, and youngest child Nathan.He owned his own home, but was still paying on a mortgage, and listed as Aliens in 1906, according to the 1920 US Census records.Are these relatives of Irving and Harry Greenstein of Massachusetts, are you sure they were from Haverhill?Only three Greenstein families are listed in 1920 in Haverhill, and just one family on Washington Street.
I also could not locate brothers Irving or Harry Greenstein in Massachusetts after 1930, perhaps you should try World War 1 US military records, and it’s possible they were in the service, or shortened their surname to Green, though I checked, and still could not locate them.I have additional information; so let me know if I’m on the right track.
