looking for info on Sarah Miller b abt 1820. Unsure of her maiden name. Had 3 sons-James W. b abt 1844, John b abt 1846, and Olin B. b11-24-1851.They appear in the 1870 census and in 1900, Olin appears with his wife and children. He died in 1903. Wife Martha (BABER) may have remarried. She died in 1954. Would like info on husband of Sarah and her birth and parents. Have tried to access 1860 back census' and can only find index-no actual records. ANY help appreciated.
