Dr. George Wallace Brown, son of George P. Brown and Sarah (Percy), was born in 1869, at Dunboyne, in the Township of Malahide, Ontario. He went to High School in nearby Aylmer, and then moved on to medical school in Toronto. George married and had at least one daughter. They moved to Port Arthur, Ontario, where they lived for about 30 years before Dr. Brown died. He underwent an operation at the Royal Victoria Hospital, in Montreal, Quebec, a few months before his death, but it was ineffective. Their daughter moved to Chicago, Illinois, USA, and presumably married.

Oscar Herbert Brown, son of George P. Brown and Sarah (Percy), was born in 1875, at Dunboyne, in the Township of Malahide, Ontario. Nothing else is currently known about him.
