I am responsible for the confusion over Gilbert's middle name. I wrote a commentary a while back on the issue of the name Maxwell in the family in response to someone who had posted it as a possible middle name for Gilbert. My conclusion was that, even though there is no documentary proof or indication that Gilbert had a middle name, it is remotely possible that it could have been Maxwell.
As a result, I do not support the use of Maxwell with Gilbert's name and will try to remove it.
