Like you, I saw William Shockley Cole listed as spouse on Martha's death certificate. It was confusing until I realized that someone misunderstood and wrote William instead of Charles.
Do you have the names of Hosea and Nancy's children? I've looked at several family trees, but I haven't been able to get all the names. A couple of them listed only the ancestor of the individual making the tree. One even had three children named John. Also, do you know the names of Hosea's parents. I saw one reference to a John Cole and Eliza Unknown.
Anything you can tell me will be much appreciated.
