Another factor in establishing a link between Dr. Edward Maddox and Cornelius Maddox is establishing a common geographic location for the two of them.  We now have an estate record showing that Edward Maddox was living in Nanjemoy, Charles County, Maryland, around the time that Cornelius arrived in Charles County in 1680.  Cornelius would go on to purchase two tracts in Nanjemoy (Tatshall and Nuthall) around 1684.  A second record shows that Edward had a business relationship with John Reddick/Reddich, the man who paid for Cornelius’ transport into Maryland in 1680.  At a time when fewer than a hundred people lived in Nanjemoy, it would be highly unlikely for the two men not to have been related.  Here are the two records:
