My name is Mary Morgan Stephens, I am a registered nurse, and I have a condition called Essential Tremor,all my living siblings have this also, to one degree or another, as do some of our children, this is a benign condition that causes shaking of the hands, it is an inherited condition. I don't know if my mother had it or not, she died in her early 40's, her mother was Lucy Ellen Dowdy Martin b. 2/22/1882 in Carlisle Co. Ky. and she had this condition with severe shaking of her hands. Lucy's parents were Thomas Dowdy b. 1859 in Ky. and Lydia Beard, b. 1856 in Ky. I'm not sure which line carried this gene but I thought it might be a relative easy way to figure out who is related to whom. If you have any information please let me know.
