Van Gelder Relationships

I created this diagram to show my Mohican ancestor John Van Gelder's relationships to the Mohicans and Wappingers around him.  The arrows represent relationships, either biological or social.  In each box I give nationality, any special position the individual may have held and the band or location of where s/he lived.  Afterward I discovered that Nimham was married to Van Gelder's sister.  I haven't been able yet to figure out how to edit the diagram to present the new information.  It's fascinating to ponder, though.
