Great grandparents came in 1900. He worked in the PA coal mines. My grandmother was born in 1907 near Wilkes-Barre. Her father got black lung and could not work. There was no disability and they tried to survive by taking in boarders. They eventually had to return to Europe. My grandmother returned to the US in 1924, as a US citizen.
My Great-Grandfather founded an Iron Workers Union in NYC, a very unusual job for a Jew.
