The inf on Martha Scott came from her husband, my Great Grandfather's pension records. Isaac Blakey aka Isaac Blaker during the Civil War.
I got the info from the National Archives in Washington DC. There were some military records on my Great Grandpa. He was injuried in the war.
I have been trying to locate where Hew Davis Plantation was or is, I haven't found it. Perhaps the name was changed.
Thanks for asking,
Susan
