Once again thanks for all the replies.  I have thought about the
problem and I think I can find all the poles graphically.  Here is
what I am thinking, but don't necessarily know how to do it.

I don't really understand the Project command well enough to do what I
want it to do.
I can Plot3D[ Re[Gamma[x+I y]]] for some region, then project onto a
plane z==some number.  I now have a curve in the x,y plane, at least
theoretically.  (In practice I just get the plane, since I must be
doing something wrong.)  If I do the same for Im[Gamma[x + Iy]] and
project onto a plane z== #.  I now have another xy plot.  I can then
use the Show command to merge the two plots.  Every intersection of
the curves should be a solution I am looking for...correct?

Does that make sense?
