The only thing I have on your request is
James Kyles 1832-1864. I found three children Mary J. Kyles 1855....William Kyles 1856.....John Jacob Kyles 1858. They are listed on the 1860 census along with wife Mary born 1830. I found it on the free site ancestry.com I am not sure if this is the mother, but I found no Eliza online. I am sure your research is right I just could not find her but did find the parents with brother and sisters. Maybe this helped a little
