When I click your profile I see you have entered some family. What I don't see is any information about Kathryn Theda Klein Vance. In your question, you stated she is your husband's great grandmother. So you should enter him as your husband, then his parents, then thier parents, and then you can connect Kathryn Theda Vance. Then, you will have a basis from which to do further research here on the Wikitree.
