UPDATE: David Velleman (Philosophy, NYU) writes:
I doubt whether any philosophical genealogy project will be interesting in the way that the mathematical project is. The mathematicians are part of an intellectual tradition that has retained its identity over centuries. Here, for example, is the genealogy of the set theorist Ken Kunen at Wisconsin (in reverse chronological order):
Gottfried Leibniz (1666)
Erhard Weigel (1650)
What are the chances that the academic genealogy of any analytic philosopher working today would reach back to 17th-century figures
who would be recognizable as philosophers, in the way that Leibniz is
recognizable as a mathematician? Pretty slight, I'd say. I'd be interested if someone could prove me wrong.
