this swaby family originated from Yorkshire, England. They owned a property, Montpelier, which I think is in Clarendon. James Joseph Swaby was a governor of Jamaica in the 1700's, his son James Joseph II lived at Montpelier and returned to England and died there. James Joseph II's daughter Ann Margaret Eleanor Swaby married Frederick Peat of St. Ann's Parish, property included Tripoli which was near Dry Harbour (now called Discovery Bay). Ann Margaret Eleanor had no siblings. James Joseph II may or may not have had siblings, given what I have found out, most likely sisters. The James Joseph I generation may have brought other Swaby relatives, as there are several Swaby families in the 1700s in Jamaica. That is what I have been able to piece together from Jamaican Family Search Free pages and Ancestry.com
