I am Vivian M. Muench my fathers daughter. My father was a brillant man but troubled. I am 1/2 german and have been given 3- very gifted daughters I was too gifted. My father's step father who raised him was Edward Mac Niel the famous sculpture. My fathers mother's name was Cecelia but not Muench. My fathers Father Muench committed suicide after a gassing? accident was ill for a long time Cecellia his wife was a nurse. Can anyone tell me my grandfathers first name so I can begin to uncover a hidden lineage. My mother and father divorced when I was 7 years old. I'd like to pass on a fuller lineage to my brillant daughters and brillant grandson.
