There’s a project/website out there that traces mathematicians’s “genealogy” through their PhD advisors, their advisor’s advisor, and so on. Now obviously I don’t have a PhD advisor, but if you look at professors I’ve simply taken courses with, I’m a direct mathematical descendent of:

Isaac Newton
Galileo
Euler (my email’s namesake)
Gauss
Leibniz
all the Bernoulli’s
Fourier
Poisson
Lagrange
Laplace
Hilbert
Felix Klein
Lipschitz
Dirichlet
Weierstrass
Bessel
Mersenne
Jacobi
Borel
Laurent Schwartz

Basically everyone. Which is not at all a sign of my mathematical brilliance, but of how explosive genealogy trees are. It’s also a nice example of why it’s so foolish to care about things like pedigree and lineage and race and family name.
