My GGrandmother Katy O. Woods who I believe was born in Nov 1861 in Illinois, possibly in Fulton County.  I am trying to determine her mother's maiden name and her birth father.

Mother's first name is Sarah and I found 2 possible marriages for her.  1] George Woods married Sarah Ann Parkins 20 Dec 1855 in Fulton Co. and 2] Henry Woods married Sarah E. McKinley 17 Sep 1857 in Fulton Co.

I do know that this marriage ended in divorce or death of husband as I next find Mrs. Sarah Woods married a George Morley 2 Jul 1868 in Geene Co, IL.  The 1880 census confirms that this is my GGrandmother as she is enumerated in the household with George Morley, age 38 and wife Sarah H, age 39 as his wife, born in IL.  Katy O. Woods is listed as his step-daughter.

Would appreciate any assistance in trying to confirm or deny the above 2 marriages as the father of Katy O. Woods and any other pertinent info on this subject.
