I found Ellen Samatha Davidson who married Frank Lawson Kibbey Feb.13.1891 Carter County,Kentucky.
The last census I found Ellen,her husband Frank and children were in the 1900 census of Kenton,Greenup County,Kentucky. I assume she died there after giving birth to her child in 1901.She was about 38 years old.
It says cause of death was Child Bed Fever,,infection in the mother following birth of a child. She is said to be buried at Grayson Memorial Cemetery,Grayson,Carter County,Kentucky.
I found Frank Lawson Kibbey died August 31,1929 in Carter County,Kentucky. He is buried at John Kibbey Cemetery,Carter County,Kentucky.
I hope this is the family you were looking for. I believe it is as her parents were Isom Davidson and Elizabeth Williams.
