Vicki, I can help you out a bit. Robert Henry was the eldest of five children. He had one brother, John and three sisters, Mary Jane, Harriet and Pheobe. His parents were Robert Drought and Pheobe Abbott. His maternal grandparents were John Abbott and Mariah Coughlan who was first married to a Thomas Searson. Mariah is my great great grandmother through her Searson children. If you would like more information, please email me at bonnie.miller@rogers.com
