Looking for Descendants of Shadrack and Elizabeth Nee Rubenstein OR Similar Dewey

I am looking for the descendants of Shadrack and Elizabeth who were the parents of
my great grandmother Clara, who married (? London Coachman ?) John Parkin and subsequently
had my Grandmother Amy and her siblings; Olive, David and Samuel. I am told that the
Rubenstein connection involves Shakers in America. Thankyou.
