I started browsing https://www.genealogy.math.ndsu.nodak.edu/ after reading this post. Some of the genealogies are wildly impressive. For example:

The Euler -> Lagrange link is sort of dodgy, though. Lagrange was an autodidact. What he got from Euler was Euler's position at court, not a doctorate, though they did collaborate on some research before that.
