HD has been in my family for many generations. I have researched back to my gggrandather Henry NICOL
in Aberdeenshire Scotland. He died in 1893 in Manitoba Canada. The death certificate doesn't mention HD but the symptoms were there. He (unknowingly) passed it on to several of his children. The surnames related to him are all located in Western Canada as far as I know. If anyone has information on these families please contact me.
