This is a subject that I find rather interesting and it occurred to me today that maybe someone else had done this. There are services available that handwriting analysts offer to give you a "profile" of ancestors from their handwriting. Some of the Hord family books by Rev. Hord have handwriting/signature samples of some of our ancestors so I wondered if anyone had done this yet. I'd love to have it and post it at my website for everybody:
