I had a researcher in Quachita Parish check for me and my Francis Sheppard died in 1863. For me, this documents for sure the date of his death. This was in the middle of the Civil War, so he may have died while fighting the war. Have you found any more information on your Francis. This means my grandmother, Flora Sheppard, was orphaned at the age of 6. Her mother married Francis in 1856 and Flora was born in 1857. In 1860, Flora is in the census with her father, Francis, and other children that belonged to her mother, Amanda (Cobb) Vickers. My grandmother Flora doesn't surface again anywhere until she is about 23 years old living in Collin County, Texas 1880 Census, being a boarder in the home of a Crane family. Would enjoy hearing from you again.
