Possibly the Ann Marryat who was left £100 in the will of Robert Kingston of Demerera (written 1814 and proved 1816), described in the will as his housekeeper. He also left £1000 to his children by her, "say, John Joseph and one not yet born".
The legacy from Robert Kingston may have enabled Ann to buy land in Demerera in January 1816: "By Henry Buckoll, Executor to the last will and testament of J. Trigger, dec. - Transport of the east half of Lot No. 98, with all the Buildings thereon, situated in Cumingsburg district - to Ann Marriott and her three children."
Will of Robert Kingston of Demerara , West Indies, PROB 11/1576/10.
