Hi Don,
Yes I have a Charles Gahm as a brother of my great grandfather. My Great Grandfather was born John Edward Gahm b.9 May 1867 in Jackson Co Ohio. his brother Charles Andrew Gahm was born 16 July 1884 in Leon Butler Co. Not sure if this is the Charles you are looking for but I have a lot of other information and names so may be another family Their Father and mother were John Jr Gahm and Mary Shear.
