These are the children of his first wife; he had four more children from his second wife Lady Margaret Stanley daughter of Thomas Stanley 2nd Earl of Derby

Son Thomas came to the island with his father, who was the personal representative of Lord Stanley, Earl of Derby, probably around the year 1530.
He seems to have stayed on the island marrying a local girl.

Does anyone know what happened to the son or the role of the father on the Island?
