A new chronology of dealings with Thomas Hussey by Edward and Cornelius Maddox in both Charles County, Maryland and Stafford County, Virginia, demonstrates a likely business handoff from Edward to Cornelius. We’ve laid them out here: Hussey-Maddox interaction 1600s.
The chronology shows that Dr. Edward Maddocks dealt directly with Thomas Hussey in Charles County, Maryland, in 1681-1686. After 1686 (just after Cornelius’ marriage), Cornelius Maddox generally deals with Thomas Hussey, receiving payments. If this is a handoff, it probably is good evidence of a father-son relationship.
