I think your mixing up a lot of facts.
The Israel Kravitz I mentioned was born in Yiscagabernov (near Skvira) in the Ukraine (they use to say Russia )probably in the 1860's or 1870's because my father was born in 1897. Israel was married in Russia to a women who died in childbirth ( her 2nd child )around 1905-1907. He came to the US in the early 1900-1910 (?). The entire group of relatives lived in the 7th Street Girard Avenue area in the early 1920's.
Some relatives are named Kravitz others are Krevitz.
My father's business address was on Brown Street.
Their were 2 Max Kravitz's - Big Max and Little Max both were my father's distant cousins.
Never heard of an Esther. There was also a Coleman Kravitz.
Israel I think married again here in the States to a woman named Fegela Brooklyn - Her name may have been Rebecca - I only know her hebrew name?
Israel worked for a company called Girard Smelting - a lead smelting company and eventually died of lead poisoning.
My father's name was Samuel (Issar ben Israel) and he had a sister named Katie.
The dates for Max, Esther, and Harry are all consistant with the time frames I mentioned.
As we say - ver vas.
Hope some of this helps.
