As soon as the topic of a lease to a chunk of Manhatten comes into Edwards genealogy it's time to mention the great genealogy scam worked on thousands of Edwards descendants. The basis of the scam was to convince people
to pay good money to establish their claim to a share of the
fabulous estate left by this Robert Edwards. Of course if
your family tree had to be altered a bit to provide the link to
Robert the scammers, for a price, would supply that, too.
The result was lots of bogus Edwards genealogies that still
linger on years later. It is, of course, possible that you have
some Robert Edwards in your line; but don't count on it.
That's generally a part of your family history that will need to
be redone.
