Sarah E. Cheney is the daughter of Edward Cheney - she was born probably in Lewis Co., KY. A lot of people have her mother being Parmelia Gano. (There is an Edward Cheney who married a Matilda Drake in 1803/4 time frame in Mason Co., KY but quite a few years from marriage to Sarah's birth.)
Sarah Whiteman is mentioned in her brother's Will - Edward Cheney in Coles/Douglas Co., IL.
Sarah Cheney & Amos Whiteman were married in Vermilion Co., IL July 27, 1836.
Amos Whiteman filed the Admin estate papers for Edward Cheney, Sarah's father, in 1836 in Vermilion Co., IL And in 1838, Amos Whiteman transferred guardianship of Sarah's younger siblings to an Isaac Moss - the cousin-in-law to Sarah. (Isaac Moss is the husband of Mary Ann Cheney, daughter of James Cheney, Edward Cheney's brother.)
Sarah's siblings include John, Edward, William, Samuel, Phebe, Susan, Celia, Nelson, Napoleon B. The first siblings were born in Kentucky, Phebe & Susan were born in Champain Co., OH, Nelson in Indiana (Warren Co.) and Napoleon in Illinois.
Sarah's father's parents are listed as Edward & Eleander. (I am guessing this Edward is from Huntingdon Co., PA and related to an Isaiah Cheney.)
