My mother's father, Edward Ryan, and Earl D. Peacock were 1/2 brothers. They had the same mother, Martha. Martha and Jonathon Peacock later divorced. As you know, Jonathon had the brewery in Rockford.
I have some college papers and postcards from 1909 that Earl sent to his mother. He went to St. Mary's College in Kansas. If you'd like to talk further, please e-mail me at firstname.lastname@example.org
