If this is any help to any of you, Sarah Ann Doublin Clement was a sister to Mary Doublin married to Thornton Bright. At her death in Livingston Co KY in 1915 she had a note in her bible that said that her sister married a Thornton Bright and that Mary had a daughter "Attie" who married a Chappell. I assume that is the Mary Beatrice bn 1886. Since the Doublins are my line, (E.Jackson Doublin was my GGFather and brother to Mary and Sarah) I am just passing it on. Possibly you can find her children or grandchildren.
