Debra:

More or less in order...

Splitting the data into two separate graphs seems reasonable.
I would clarify that you don't put "copies" of the nodes in the new graph
(in the sense that you are creating new objects) but references to the same
objects.

The way that you're describing what you've been doing suggests to me that
you're somewhat confused between
(a) the data model (i.e., representation in terms of data structures)
(b) the visualization of that data

You can certainly create a visualization that displays more than one graph.
 There is sample code in the distribution that gives examples of doing this.

Some technical details:
* You can declare your graph as Graph<Women, String> (or if you have an
relation object that represents the relation, Graph<Women, Friendship> and
Graph<Women, History>) rather than extracting the ID from your Women
object.  That way it's more clear what the Graph represents, and you have
all the information in the original object in the same place.  (Nor does it
take up more space--the opposite, in fact, since you're not creating a new
Integer object for each vertex.)
* The easiest way to add each of the Women objects to both graphs is just
to add them both in the same loop, as below.  (In any case, addVertex()
takes a single vertex--in this case, an Integer--and calling it on a
Collection<Integer> won't work.)

  static Graph<Integer, String> g;

  static Graph<Integer, String> g2;

  for (Women aWoman : GaleShapely2.womenList) {

  g.addVertex(aWoman);

  g2.addVertex(aWoman);

  }


Hope this helps.

PS: FYI, you sent this to the owner of the jung-support list rather than to
the list itself; I've taken the liberty of redirecting my response.
Also, support questions are best sent to StackOverflow these days; that's
where most of the questions relating to JUNG are being asked and answered.
