I have a GGG Grandfather Nicholas Cole Grose who married Mary Biddulph. He was a Captain in the Army maybe in Jamaica. They had a daughter Mary Biddulph Grose who married Robert Lindsay Milligan Gregory in Jamaica and later came to Australia in 1853. I have a photo of Capt. Nicholas Cole Grose taken in Sydney but have not yet been able to date it. Nicholas is supposed to have had a second wife.Mary Biddulph Grose is said to have been an heiress. Do you know of any of these people?
