According to data gathered, there are four different HYMOFF families in the USA. The original immigrants were:
(my great grandfather)ISRAEL HYMOFF who entered the US from Lublin, Poland in 1889 and settled in Boston (Roxbury). ISRAEL married Adeline KADETSKY WATERS a widow with children. They had a son, Gustav (lived in Dorchester, MA) and daughters Sara (Rosenberg), Dora (Cohen & Booke), Charlotte (Lesser) and Grace (Schildmeyer). All but Grace stayed in Massachussetts, she and her children settled in California.
HYMAN or HERMAN and ETTA HYMOFF, from Iasi (Jassy) Romania, arrived in the US in 1909 and had children Max, Joseph, Vitei Samuel and Hyman and settled in Brockton, MA.
JACOB and CHASSIE IDA HYMOFF, arrived in the US in 1906 with son CARL (EARL) and then had Leo, Annie, Nathan, Lena and George. They lived in Dorchester and Brookline, MA.
There were other Hymoff sisters who settled in England and S. Africa and the US (LEAH HYMOFF SALKIN) who came from Lutsk, (has been Russia, Poland and Ukraine)
Possible alternative spellings include HAIMOFF, HEIMOFF, CHAIMOV, CHAEMOW, Haimovitz, Haimovich?
We are all working together to not only find our ancestors but see if we share any. It might not be a coincidence that all four familes came to settle in Massachusetts.
