I am looking to get past a dead end in the form of my 3rd Great Grandmother Prudence (Prudens) Cooper. She was born about 1846 in New York. She Married Edwin Palmer in Kankakee, Illinois in 1868. The 1880 Census shows them living in Salina, Kankakee County, Illinois. I believe (from a family diary) they lived in Custer Park, Will County, Illinois by about 1890. Edwin was born about 1846, in Illinois, died in 1922 in Will County, Illinois. They had three children I know of: Sarah C., Jessy J., and Willis E. Any help finding the parents of either of these individuals would be appreciated. I would also like to see copies of any photo available.
