I am the mother of Hugh Chapman's grandson, Morley Thomas and the widow of Tobias Hugh, son of Hugh Chapman.
Do you know of Eric Byas Chapman living near London (?). From what I can determine, he became a pharmacist.
Toby's father, Hugh was a Gold Medalist at University of Toronto and a pharmacist too. Illness interrupted his career.
Toby did not know his father beyond the toddler years. It affected him deeply.
I would love to learn about the Chapman family if any one would be willing and able to speak with me. Do you know of such a one?
