I did find a David and Mary Cox but didn't know if that could possible be Isabel's parents. Our family records if, I remember right, did not have the parent's of Isabel listed. We moved into a new home June 1st and I am still unpacking.
I have that Benjamin Cyrus and Isabel had seven children all born in Carey, Wyandot, Ohio
Rachel b.1849
Cyrus b.1845,
Melissa b.1846,
Mary b.1847
Fredrick b.1849
David b.1853
Sarah b. 1857
Fredrick and Rachel were twins and Fredrick is buried in Nordon, Keya PAha, Nebraska.

Thank you for your help.
Diane
