This is the JMU Math & Stat Department Family
Forest (though it actually contains a circuit), according to the
Mathematics Genealogy Project
(as of Feb. 1, 2013).
NOTE: if two advisors are listed for a particular mathematician, I have
included only the first one (exception: the two people in the department
for whom two advisors are listed).
The vertical position of a name corresponds (at least approximately) to the
year of her/his doctorate.
