Suggested edit: While researching Isham's father Williamson Finch, I discovered that the memorial listed as his father is instead for Henry Finch who had no record of the name William or Williamson and died in 1868 in Choctaw County, Mississippi. Henry Finch was married to who is believed to be Mamie Parmer according to their family Bible. Isham's father Williamson had no record of the name Henry and never lived in Mississippi and likely died in Carroll County, Tennessee c1865. He does not have a memorial yet. Williamson Finch was married to Mary Carter who is correctly listed as Isham's mother as is one of his correct siblings, Green Finch, and one cousin incorrectly listed as a sibling, Williamson Riley Finch. At some point, while researching these families an error occurred and Williamson's and Henry's profiles were combined into one person. I'm attempting to fix this now.
