Looking for Descendants of Two Riley Brothers Immigrants from Derbyshi

Looking for descendants of two Riley brothers,immigrants from Derbyshire,U.K.
in the 1800's. Their brother Walker Riley,&wife Betsy immigrated to join them, but returned to England after two years due to the death of their first child, Francesca Maria. Family records the occupations of the two brothers as farmers,possibly cattle, as their father was a butcher/grazier in England.
