You should still go to the Family Search and play around there. This is what I found. There is a Mrs. Lydia A. Keller, who was born in Zyleski, Ohio (Vinton County) in 1858, who died 22 December, 1909 and the informant gives her parents as Archibald Brooks, and Annis Drain. The "A" in Lydia A. Keller could be Amanda. She could have been remarried. It's worth checking out. If this isn't her, it's a sibling. Mrs. Keller died in Nelsonville, in Athens Countyy, Ohio.
