William Witt is a real person with real facts. There is no evidence that he was a Huguenot. We really want to have only documented facts for real people.
Guillaume Witt, Huguenot, is a different profile. None of the information associated with Guillaume Witt has documents. We have looked for documentation ands not found any. Therefore he has been Labelled "Disproven Existence.":
We chose to keep the two profiles because there is material about "Guillaume Witt", Huguenot, out on the internet which we did not want to get mixed up with William Witt, the real person. Perhaps that was a mistake. The alternative woudl be to merge the two profiles together and treat the fictional Guillaume Witt, Huguenot, material under Research Notes. It should not be included under Biography because there is no documentation for it.
But how we deal with the information is secondary. Getting it is primary. There are certainly people who are attached to the idea of Huguenot ancestry, but no reliable documentation has yet been found for it. The only way to really resolve the issue is to find the documentation.
