Following on with Rebecca Dennis, her two children sadly died within days of each other in January 1852 - William was 4 and Mary 2. Rebecca had passed away the year before in July, as did her mother Charlotte, a very sad time for the Dennis family. It would be very interesting to find out the cause of death of all four. John Gibson had remarried on 31 December 1851, 6 months after Rebecca had died. His new bride was 20 years old when they married, presumably William and Mary lived with them until their untimely deaths a few short weeks later.
John & Hannah went on to have 8 children, 2 of whom died in infancy.
