I have a subscription to Ancestry and found a few things about Mandy Mae Stephens. You may already have them though. Someone has a family website where she is listed as Mandy May Stephens Thacker. Shows she married George "it"Campbell on 8/16/1913 in Floyd Co. Ky. Says she was born 1896 and died 9/3/1945. She is listed on the 1920 census for Floyd Co. Ky. living in Depot, Ky. Shows her as married to George, she is 19 and has 2 children, Harris and Johnie. Her death certificate is online at Ancestry. com but hard to read. It says she was 49 and died from pulmonary TB. Shows the parents you mentioned for her but not her mother's maiden name. The Volumn # is 38 and death certificate is#18768. Ky usually charges $6 or $7 for a copy. Ancestry.com has her name as Mardy Campbell. Think it is because the death certificate is so hard to read. Also the family website had her as Amanda, Manda and Mandy. Hope this helps some. Not sure where the Thacker name comes in unless she remarried. If you have a fax machine I can download the death certificate and fax it to you.
