My wife's family Bible notes that Bradley Yeomans first married a Catherine --? before marrying Sarah E. Austin.
My wife has the original marriage certificate of Bradley Youmans and Sarah E. Austin on 5 February,1857 at Fishkill Landing, New York. They had five children, Catharine Louisa, Festus, Loretta, Adreanna, and Cenna (who died as a child). Sarah Evaline Austin was born 21 May, 1835, the daughter of Daniel & Abigail Austin of Peekskill, N.Y. She died in Rantoul, Illinois, February 14, 1913. Bradley Youmans died 11 January, 1887 in Illinois.
We have other resources that also note Esther Organ & Abijah Youmans as Bradley's parents, but do not have official verification.
